Product details
Overview
CY74FCT16374TPVCT from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit or unified 16-bit operation, 5 V ±10% supply, industrial temperature range (−40°C to +85°C), 64 mA sink / 32 mA source drive capability, and TSSOP/SSOP-compatible 48-pin SSOP package. It serves as a high-drive buffered register for bus interfacing in backplane and high-capacitance load applications.
For engineers reviewing the CY74FCT16374TPVCT datasheet, CY74FCT16374TPVCT pinout, CY74FCT16374TPVCT application, or CY74FCT16374TPVCT equivalent, key selection criteria include propagation delay (max 10.0 ns), output skew (<250 ps), Ioff-enabled partial-power-down support, ground bounce performance (VOLP <1.0 V), and 3-state output enable control.
Technical Context
The CY74FCT16374TPVCT implements two independent 8-bit register banks sharing common clock (CLK) and output enable (OE) inputs, enabling flexible data latching across wide buses. Its flow-through pinout minimizes trace routing complexity on dense PCBs.
It features Ioff circuitry that disables outputs during power-down to prevent current backflow, and edge-rate control circuitry to suppress switching noise-critical for stable operation in mixed-signal environments with sensitive analog sections or high-speed clocks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC | 5 V ±10% - compatible with legacy 5 V TTL/CMOS systems without level-shifting |
| tPLH/tPHL | Max 10.0 ns - supports >100 MHz clock domains in registered bus architectures |
| IOL/IOH | 64 mA sink / 32 mA source - drives heavy capacitive loads (e.g., >100 pF traces or backplanes) |
| VOLP | <1.0 V at VCC = 5 V, TA = 25°C - limits ground bounce-induced logic errors in multi-load systems |
| tSK(O) | 0.5 ns - ensures tight timing alignment across all 16 outputs for synchronous sampling |
| Operating Temp | −40°C to +85°C - qualified for industrial control, motor drives, and base station infrastructure |
| Ioff | ±1 µA at VCC = 0 V - enables safe hot-insertion and partial system power-down |
Pinout & Package
Package: 48-lead SSOP (O48), 300-mil body width, JEDEC MO-118 compliant, 0.025" pitch, 1.2 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–8, 13–20, 25–32, 37–44 | Data Inputs (D1–D16) | Asynchronous parallel data inputs; each pair (e.g., 1D1–1D8, 2D1–2D8) feeds one 8-bit register bank |
| 9, 21, 33, 45 | Clock Inputs (1CLK, 2CLK) | Positive-edge-triggered clock for respective 8-bit banks; tied together for 16-bit operation |
| 10, 22, 34, 46 | Output Enable (1OE, 2OE) | Active-low 3-state control; enables/disables corresponding 8-bit output groups independently |
| 11–12, 23–24, 35–36, 47–48 | Outputs (1O1–1O8, 2O1–2O8) | Registered, 3-state outputs; flow-through layout aligns inputs and outputs on opposite sides for minimal trace length |
| 17, 18, 30, 31 | VCC | Four dedicated 5 V supply pins - reduce IR drop and improve noise immunity across wide die |
| 14, 15, 27, 28, 40, 41 | GND | Six ground pins - provide low-inductance return paths for high-current switching outputs |
Key Features
| Feature | Design Value |
|---|---|
| Ioff partial-power-down | Prevents damaging backflow current when VCC = 0 V, enabling live insertion into powered backplanes |
| Edge-rate controlled outputs | Reduces EMI and crosstalk in high-density routing; eliminates need for external series termination resistors |
| Flow-through pinout | Input and output pins aligned on opposing edges - simplifies layer stackup and reduces vias in 4+ layer PCBs |
| High drive strength (64 mA sink) | Drives long traces, unterminated stubs, or multiple TTL loads without signal degradation or timing violations |
| Low ground bounce (VOLP <1.0 V) | Maintains logic LOW integrity under full-output switching, preventing false triggering of downstream receivers |
Applications
| Industrial Backplane Interface | Programmable Logic I/O Expansion |
|---|---|
|
Use Scenario: Interfacing FPGA or microcontroller GPIO to a 16-bit parallel backplane with >80 pF trace capacitance and multiple slot connectors. IC Role / Device Role / Timing Role: Registered buffer providing setup/hold margin, drive strength, and isolation between controller and noisy backplane environment.

IC Role / Device Role / Timing Role: Active repeater restoring signal amplitude, slew rate, and timing margins degraded by long cable runs or multiple loads. Use Value: 32 mA source / 64 mA sink capability re-drives weakened signals; edge-rate control suppresses reflections on unterminated buses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit registered buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16374CTPVC | 5.2 ns max propagation delay (vs. 10.0 ns); identical pinout, drive strength, and Ioff support | Better suited for >150 MHz clock domains where tighter timing margins are required | Select when system timing budget demands sub-6 ns register-to-output delay |
| CY74FCT162374TPVCT | 24 mA balanced drivers (vs. 64/32 mA asymmetrical); lower ground bounce (VOLP <0.6 V); no high-drive mode | Optimized for transmission-line driving with reduced EMI; unsuitable for high-capacitance backplanes | Choose for point-to-point or daisy-chained transmission lines where impedance matching and low noise supersede raw drive strength |
Compared with CY74FCT16374CTPVC, the CY74FCT16374TPVCT trades speed for cost and thermal headroom; compared with CY74FCT162374TPVCT, it prioritizes high-current drive over signal integrity on matched lines-making CY74FCT16374TPVCT optimal for legacy 5 V bus buffering where load capacitance exceeds 50 pF.

FAQ
What is the maximum clock frequency supported by CY74FCT16374TPVCT?
The CY74FCT16374TPVCT has a maximum propagation delay of 10.0 ns (tPLH/tPHL) and minimum clock pulse width of 5.0 ns (tW). This supports reliable operation up to approximately 100 MHz in well-terminated systems. For sustained 100+ MHz use, layout optimization and load capacitance ≤50 pF are recommended. The CY74FCT16374TPVCT datasheet specifies timing under industrial temperature and voltage conditions.
Does CY74FCT16374TPVCT support hot-swap or live insertion?
Yes, CY74FCT16374TPVCT supports hot-swap via its Ioff circuitry, which disables outputs and limits leakage to ±1 µA when VCC = 0 V. This prevents current backflow into a powered backplane during insertion. However, proper sequencing of GND-first/metal-shell-first mechanical design and board-level TVS protection remain essential for full hot-swap compliance. The CY74FCT16374TPVCT specification explicitly validates this behavior per MIL-STD-883.
Can CY74FCT16374TPVCT be used as two independent 8-bit registers?
Yes, CY74FCT16374TPVCT contains two functionally independent 8-bit register banks (Bank 1: pins 1–8, 9, 10, 11–12; Bank 2: pins 13–20, 21, 22, 23–24). Each bank has dedicated CLK and OE inputs, allowing asynchronous latching and 3-state control. Tie 1CLK to 2CLK and 1OE to 2OE only when unified 16-bit operation is required. This flexibility is confirmed in the CY74FCT16374TPVCT functional description and pin configuration diagram.
What is the purpose of the multiple VCC and GND pins on CY74FCT16374TPVCT?
CY74FCT16374TPVCT provides four VCC and six GND pins to minimize power distribution impedance and suppress simultaneous switching noise. This layout reduces voltage droop during full 16-bit output transitions and lowers ground bounce (VOLP <1.0 V), directly improving signal integrity in high-drive applications. The pin assignment is optimized per the CY74FCT16374TPVCT mechanical drawing and electrical characterization data.
Is CY74FCT16374TPVCT RoHS compliant and lead-free?
Yes, CY74FCT16374TPVCT is RoHS compliant and lead-free, with "Green (RoHS & no Sb/Br)" eco-plan designation and CU NIPDAU lead finish. It meets JEDEC MSL Level-1 (260°C peak reflow) and is supplied in tape-and-reel packaging (1000 units/reel). This compliance is documented in TI's official packaging addendum for CY74FCT16374TPVCT and verified through TI's material declarations.
