Product details
Overview
CY74FCT16374ATPVCT from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, 64 mA sink/32 mA source drive strength, 6.5 ns max propagation delay (CLK to O), and industrial −40°C to +85°C operation at 5V ±10%. It serves as a high-drive buffered register for backplane and bus interface applications in industrial control and data acquisition systems.
For engineers reviewing the CY74FCT16374ATPVCT datasheet, CY74FCT16374ATPVCT pinout, CY74FCT16374ATPVCT application, or CY74FCT16374ATPVCT equivalent, key selection criteria include output drive capability (64 mA sink), Ioff partial-power-down support, ground-bounce performance (VOLP <1.0 V), flow-through pinout for PCB layout simplification, and SSOP-48 packaging compatibility with high-density routing.
Technical Context
This device implements two independent 8-bit registers or one unified 16-bit register via shared clock (CLK) and output enable (OE) inputs. Its TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V) and hysteresis (100 mV) ensure robust noise immunity in noisy industrial environments.
The register uses positive-edge-triggered clocking with 2.0 ns minimum setup time and 1.5 ns hold time. Output three-state control is active-low on OE, enabling bus sharing. Ioff circuitry disables outputs during power-down to prevent current backflow, supporting partial-power-down system architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - compatible with standard TTL/CMOS logic rails; no external regulation required |
| Propagation Delay | 6.5 ns max (CLK to O) - supports ≥150 MHz clock domains in registered data paths |
| Output Drive | 64 mA sink / 32 mA source - drives high-capacitance backplanes and unterminated stubs without external buffers |
| Ground Bounce (VOLP) | <1.0 V at VCC = 5 V, TA = 25°C - minimizes signal integrity degradation during simultaneous switching |
| Operating Temperature | −40°C to +85°C - qualified for industrial automation, motor control, and factory instrumentation |
| Ioff Support | Enabled - prevents damaging current flow when VCC = 0 V and I/O pins are biased, critical for hot-swap and multi-rail systems |
| 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, JEDEC MO-118 compliant, 0.025-inch pitch, 1.2 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–8, 17–24, 33–40, 41–48 | Data Inputs (D1–D8, D9–D16) | Asynchronous parallel data inputs; flow-through arrangement aligns inputs and outputs on opposite sides for minimal trace length |
| 9, 25 | Clock Inputs (1CLK, 2CLK) | Positive-edge-triggered clock for respective 8-bit sections; enables independent or synchronized register operation |
| 10, 26 | Output Enable (1OE, 2OE) | Active-low three-state control per 8-bit bank; allows dynamic bus isolation without external logic |
| 11–16, 27–32 | Outputs (1O1–1O8, 2O1–2O8) | Registered, three-state outputs with high-current drive; pin-mapped to corresponding inputs for direct routing |
| 19, 20, 30, 31 | GND | Four dedicated ground pins - reduce ground bounce and improve noise margin in high-speed switching |
| 13, 14, 28, 29 | VCC | Four dedicated power pins - lower supply impedance and stabilize VCC under transient load conditions |
Key Features
| Feature | Design Value |
|---|---|
| Ioff partial-power-down | Enables safe integration into multi-voltage systems where VCC may be sequenced or powered off independently |
| Edge-rate control circuitry | Reduces EMI and crosstalk by limiting output slew rate without compromising propagation delay |
| Flow-through pinout | Minimizes PCB layer count and trace skew - input-to-output signal path crosses package only once |
| Typical output skew < 250 ps | Ensures tight timing alignment across all 16 outputs, critical for synchronous bus capture and parallel ADC/DAC interfacing |
| Balanced 24 mA drivers (variant-dependent) | Not applicable to CY74FCT16374ATPVCT - this feature belongs exclusively to CY74FCT162374T family members |

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 |
|---|---|---|---|
| CY74FCT162374ATPVCT | 24 mA balanced output drivers; lower VOLP (<0.6 V); reduced switching noise; no 64 mA sink capability | Optimized for transmission-line driving with controlled impedance matching; unsuitable for high-current backplane loads | Select when driving terminated 50-Ω lines or when ground bounce must be minimized below 0.6 V; not drop-in due to drive strength mismatch |
| SN74ALVCH16374DGGR | 3.3 V only (1.65–3.6 V); 24 mA drive; 3.5 ns max tPD; no Ioff; different pinout | Designed for low-voltage, low-power portable and telecom systems; incompatible with 5 V bus environments | Select only for new 3.3 V designs requiring faster timing and lower power; requires full schematic and layout revision |

FAQ
What is the maximum clock frequency supported by CY74FCT16374ATPVCT?
CY74FCT16374ATPVCT has a maximum propagation delay of 6.5 ns (CLK to O), supporting reliable operation up to approximately 150 MHz in well-designed PCB layouts with controlled impedance and proper decoupling. The minimum clock pulse width is 5.0 ns, confirming suitability for high-speed synchronous bus applications. Actual achievable frequency depends on system-level timing margins including setup/hold and board trace delays.
Does CY74FCT16374ATPVCT support partial-power-down mode?
Yes, CY74FCT16374ATPVCT fully supports partial-power-down mode via its Ioff circuitry. When VCC = 0 V, the outputs are disabled and high-impedance, preventing damaging current backflow from live I/O lines into the unpowered device. This feature is explicitly specified in the datasheet and tested per industry standards, making CY74FCT16374ATPVCT suitable for hot-swap and multi-rail power architectures.
What is the output drive capability of CY74FCT16374ATPVCT?
CY74FCT16374ATPVCT provides 64 mA sink current and 32 mA source current per output, as confirmed in the "CY74FCT16374T Features" section of the datasheet. This high drive strength enables direct interfacing with high-capacitance loads (e.g., backplanes >100 pF) and low-impedance stubs without external buffers, distinguishing it from lower-drive variants like CY74FCT162374T.
Is CY74FCT16374ATPVCT pin-compatible with CY74FCT162374ATPVCT?
No, CY74FCT16374ATPVCT is not pin-compatible with CY74FCT162374ATPVCT. Although both use 48-pin SSOP packaging and share identical pin counts and power/ground pin locations, their output driver characteristics and internal current-limiting structures differ fundamentally. The datasheet confirms distinct electrical specifications (e.g., 64 mA vs. 24 mA drive), and no documentation states pin-to-pin equivalence - substitution requires verification of timing, drive, and noise behavior in the target application.
What package type and dimensions does CY74FCT16374ATPVCT use?
CY74FCT16374ATPVCT uses a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width, JEDEC MO-118 compliant, 0.025-inch pitch, and 1.2 mm maximum height. Mechanical drawings confirm body dimensions of 15.75 mm × 7.50 mm (DL package), with four dedicated VCC and four GND pins to minimize supply noise - critical for maintaining signal integrity in high-speed 16-bit register operation.
