Product details
Overview
CY74FCT16374TPVC from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, 10 ns max propagation delay (CLK to O), 64 mA sink / 32 mA source output drive, and industrial −40°C to +85°C operation at 5V ±10%. It serves as a high-speed bus interface register in memory address latching and data buffering applications.
For engineers reviewing the CY74FCT16374TPVC datasheet, CY74FCT16374TPVC pinout, CY74FCT16374TPVC application, or CY74FCT16374TPVC equivalent, key selection criteria include its 10 ns speed grade, SSOP-48 package, Ioff partial-power-down support, ground-bounce performance (VOLP <1.0 V), and compatibility with 5V TTL/CMOS systems requiring robust bus driving.
Technical Context
The CY74FCT16374TPVC implements two independent 8-bit registers or one unified 16-bit register via shared clock (CLK) and output enable (OE) inputs. Its flow-through pinout minimizes trace routing complexity on dense PCBs.
It features Ioff circuitry for partial-power-down protection, edge-rate control to suppress switching noise, and balanced output drivers optimized for high-capacitance loads and low-impedance backplanes - not transmission lines (a distinction reserved for the CY74FCT162374T variant).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - compatible with standard 5V TTL logic rails and legacy industrial power domains. |
| Propagation Delay (tPLH/tPHL) | 10 ns max - enables reliable operation in 100 MHz system clocks with sufficient setup/hold margin. |
| Output Drive | 64 mA sink / 32 mA source - drives heavy capacitive loads (e.g., >100 pF buses) without external buffers. |
| Ground Bounce (VOLP) | <1.0 V at VCC = 5 V, TA = 25°C - reduces signal integrity risk during simultaneous switching outputs. |
| Operating Temperature | −40°C to +85°C - qualified for industrial environments including factory automation and motor control cabinets. |
| Ioff Support | Enabled - prevents backflow current when powered down, critical for hot-swap and multi-rail power sequencing. |
| ESD Rating | >2000 V HBM - withstands handling and board-level electrostatic discharge in manufacturing and field service. |
Pinout & Package
Package: 48-pin SSOP (Shrink Small Outline Package), 300-mil body width (DL drawing), JEDEC MO-118 compliant, 0.630" × 0.370" footprint, 1.02 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1D1–1D8, 2D1–2D8 | Data Inputs (two 8-bit groups) | Asynchronous parallel data inputs; each group latches independently on rising CLK edge when OE is active low. |
| 1CLK, 2CLK | Independent Clock Inputs | Rising-edge-triggered clocks for respective 8-bit sections - supports split-clock domain operation. |
| 1OE, 2OE | Active-Low Output Enables | Tri-states corresponding 8-bit output banks; allows interleaved bus sharing or dynamic partitioning. |
| 1O1–1O8, 2O1–2O8 | Three-State Outputs | Registered, buffered outputs with high-current drive; share common VCC/GND pairs for noise isolation. |
| VCC (Pins 24, 48) | Power Supply | Dual VCC pins reduce IR drop and supply impedance across 16-bit bus; decoupling required at both locations. |
| GND (Pins 1, 25) | Ground Reference | Dual GND pins provide low-inductance return paths; critical for maintaining VOLP spec under fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| Ioff partial-power-down | Prevents damaging backflow current when VCC = 0 V and I/O pins are driven externally - essential for mixed-voltage hot-swap systems. |
| Edge-rate controlled outputs | Reduces di/dt-induced crosstalk and EMI by limiting slew rate - improves signal integrity on shared PCB traces. |
| Typical output skew < 250 ps | Ensures tight timing alignment across all 16 outputs - critical for synchronous bus capture and DDR-style interfaces. |
| Flow-through pinout | Input-to-output signal path follows linear left-to-right layout - simplifies layer stack routing and reduces vias in high-density designs. |
| Industrial temperature range | Validated operation from −40°C to +85°C - supports deployment in uncontrolled ambient environments like outdoor kiosks or industrial PLCs. |
Applications
| Memory Address Latching | High-Speed Data Bus Buffering |
|---|---|
Use Scenario: Latching 16-bit address bus signals between microcontroller and external SRAM or flash memory. IC Role / Device Role / Timing Role: Edge-triggered register capturing address values on rising CLK edge; OE controls bus release timing. Use Value: Eliminates need for discrete latch ICs while providing guaranteed 10 ns propagation delay and 64 mA drive for long trace runs. |
Use Scenario: Isolating and strengthening bidirectional data bus signals between FPGA and peripheral ASICs. IC Role / Device Role / Timing Role: Registered buffer with tri-state outputs synchronized to system clock; enables clean bus arbitration. Use Value: Reduces ground bounce (<1.0 V) and skew (<250 ps) across all 16 bits - preserves data eye margin at 50+ MHz bus rates. |
| Industrial I/O Expansion | Legacy System Interface Bridging |
Use Scenario: Expanding GPIO count in programmable logic controllers using parallel I/O modules. IC Role / Device Role / Timing Role: Synchronized input capture and output staging register; supports deterministic scan-cycle timing. Use Value: Ioff support allows safe insertion/removal while other system rails remain active - meets IEC 61000-4-2 compliance requirements. |
Use Scenario: Interfacing modern microcontrollers to legacy 5V TTL peripherals (e.g., UART transceivers, display drivers). IC Role / Device Role / Timing Role: Level-shifting and timing-aligned register between mixed-voltage subsystems. Use Value: 5V-tolerant inputs and robust 32 mA/64 mA outputs eliminate need for external level shifters or driver arrays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16374ATPVC | 6.5 ns max propagation delay; otherwise identical electrical specs and pinout. | Better suited for 125 MHz+ clock domains where tighter timing margins are required. | Select when system timing budget demands sub-7 ns register delay; same SSOP-48 footprint and thermal profile. |
| CY74FCT162374TPVC | 24 mA balanced output drivers; lower VOLP (<0.6 V); no 64 mA sink capability. | Optimized for transmission-line driving (e.g., LVDS stubs, unterminated buses), not high-capacitance backplanes. | Choose for reduced ground bounce in point-to-point interconnects; avoid for heavy bus loading (>50 pF per line). |
Compared with CY74FCT16374ATPVC, the CY74FCT16374TPVC trades 3.5 ns of speed for broader voltage margin and identical thermal behavior; versus CY74FCT162374TPVC, it delivers 2.7× higher sink current at the cost of slightly higher ground bounce - making it the preferred choice for legacy 5V bus termination.

FAQ
What is the maximum clock frequency supported by CY74FCT16374TPVC?
The CY74FCT16374TPVC has a maximum propagation delay of 10 ns (tPLH/tPHL), supporting reliable operation up to approximately 100 MHz in systems with adequate setup/hold timing margins. Its minimum clock pulse width is 5.0 ns, and it requires ≥2.0 ns data setup and ≥1.5 ns hold time relative to the rising clock edge - all verified across the full −40°C to +85°C industrial temperature range. The CY74FCT16374TPVC is not characterized for continuous operation beyond this frequency.
Does CY74FCT16374TPVC support partial power-down mode?
Yes, CY74FCT16374TPVC includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow from live I/O pins into the unpowered device. This feature is fully specified per JEDEC standards and enables safe use in hot-swap, multi-rail, or power-gated systems - a key differentiator from non-Ioff logic families. The CY74FCT16374TPVC maintains this protection across its entire industrial temperature range.
What package type and dimensions does CY74FCT16374TPVC use?
CY74FCT16374TPVC uses a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width (package drawing DL), measuring 18.29 mm × 9.40 mm × 4.90 mm (L × W × H). It complies with JEDEC MO-118 and features gull-wing leads with 0.630" × 0.370" footprint, 0.025" pitch, and RoHS-compliant CU-NiPdAu lead finish. The CY74FCT16374TPVC is not offered in TSSOP or other variants.
How does CY74FCT16374TPVC differ from CY74FCT162374TPVC in output drive capability?
CY74FCT16374TPVC provides 64 mA sink and 32 mA source drive per output, optimized for driving high-capacitance buses and low-impedance backplanes. In contrast, CY74FCT162374TPVC offers balanced 24 mA sink/source with built-in current-limiting resistors - reducing ground bounce to <0.6 V but sacrificing drive strength. The CY74FCT16374TPVC is the correct choice when load capacitance exceeds 80 pF or termination resistance is below 50 Ω.
Is CY74FCT16374TPVC pin-compatible with other speed grades in the same family?
Yes, CY74FCT16374TPVC is fully pin-compatible with CY74FCT16374ATPVC (6.5 ns) and CY74FCT16374CTPVC (5.2 ns) - all share identical SSOP-48 pinout, power/ground assignments, and functional pin definitions. This allows direct speed-grade substitution without PCB redesign, provided timing constraints and thermal dissipation are validated for the target application. The CY74FCT16374TPVC remains functionally identical across all speed variants.
