Product details
Overview
74FCT16374TPVCTG4 from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit bank capability, 10 ns propagation delay (tPLH/tPHL), 64 mA sink/32 mA source drive strength, and industrial-grade operation from −40°C to +85°C. It serves as a high-speed bus interface register in backplane and memory subsystem applications requiring robust noise immunity and low ground bounce.
For engineers reviewing the 74FCT16374TPVCTG4 datasheet, 74FCT16374TPVCTG4 pinout, 74FCT16374TPVCTG4 application, or 74FCT16374TPVCTG4 equivalent, key selection criteria include its 10 ns speed grade, SSOP-48 package with flow-through pinout, Ioff partial-power-down support, and compatibility with 5V ±10% supply rails in high-capacitance load environments.
Technical Context
The 74FCT16374TPVCTG4 implements two independent 8-bit registers sharing common clock (CLK) and output enable (OE) inputs, enabling flexible 8- or 16-bit data latching. Its TTL-compatible inputs accept VIH ≥ 2.0 V and VIL ≤ 0.8 V, while outputs deliver rail-to-rail swing under defined load conditions.
It features Ioff circuitry that disables outputs during power-down to prevent current backflow, and edge-rate control circuitry that limits slew rate to reduce system-level switching noise. Output skew is specified at ≤0.5 ns across all channels within the same package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10 ns max (CLK to O); enables synchronization in 100 MHz bus systems with margin |
| Output Drive | 64 mA sink / 32 mA source; drives heavy capacitive loads (e.g., >50 pF traces or backplanes) |
| Supply Voltage | 5 V ±10%; operates reliably across full industrial voltage range without regulation |
| Operating Temperature | −40°C to +85°C; qualified for industrial control, telecom infrastructure, and embedded computing |
| Input Hysteresis | 100 mV; improves noise immunity on noisy PCBs or long trace interconnects |
| Ground Bounce (VOLP) | <1.0 V at VCC = 5 V, TA = 25°C; minimizes logic errors during simultaneous output switching |
| Ioff Support | Active at VCC = 0 V; prevents backfeed current in hot-swap or partial-power-down systems |
Pinout & Package
74FCT16374TPVCTG4 is housed in a 48-pin SSOP (Shrink Small Outline Package), 300-mil body width, JEDEC MO-118 compliant, with 0.025-inch pitch. Pin 1 is marked by a beveled corner; package dimensions are 18.54 mm × 7.59 mm × 2.39 mm (L×W×H).

| 10, 22, 30, 42 | Output Enable (OE1, OE2) | Active-low three-state control; independently enables/disables each 8-bit output bank |
| 11–12, 23–24, 33–36, 45–48 | Outputs (O1–O16) | Three-state CMOS/TTL-compatible outputs; flow-through layout simplifies PCB routing |
| 17, 18, 31, 32, 45, 46 | VCC | Primary 5V supply pins; distributed across package to reduce IR drop and noise coupling |
| 19, 20, 33, 34, 47, 48 | GND | Dedicated ground pins adjacent to VCC; ensures low-inductance return paths for switching currents |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| CY74FCT16374CTPVCTG4 | 5.2 ns propagation delay; higher speed grade; identical pinout and DC specs | Better suited for 100+ MHz synchronous buses where tighter timing margins are required | Select when system clock exceeds 83 MHz and setup/hold slack is constrained |
| 74FCT162374TPVCTG4 | 24 mA balanced drivers; lower ground bounce (<0.6 V); current-limiting resistors integrated | Optimized for transmission-line driving (e.g., 50 Ω traces); reduced need for external termination | Select for point-to-point high-speed links or when minimizing undershoot on long traces is critical |
Compared with CY74FCT16374CTPVCTG4, the 74FCT16374TPVCTG4 trades 5.2 ns speed for broader voltage margin and cost efficiency in sub-100 MHz systems; versus 74FCT162374TPVCTG4, it prioritizes raw drive strength over line-matching precision-making it preferable for backplane fanout over controlled-impedance routing.

FAQ
What is the maximum clock frequency supported by the 74FCT16374TPVCTG4?
The 74FCT16374TPVCTG4 has a maximum propagation delay of 10 ns (tPLH/tPHL), supporting reliable operation up to approximately 83 MHz in systems with adequate setup/hold margin. Its minimum clock pulse width is 5.0 ns, and it meets timing specifications across the full industrial temperature range (−40°C to +85°C) and 5V ±10% supply.
Does the 74FCT16374TPVCTG4 support partial power-down, and how is it implemented?
Yes, the 74FCT16374TPVCTG4 supports partial power-down via its Ioff circuitry. When VCC = 0 V, the outputs enter a high-impedance state and leakage current is limited to ±1 µA (IOFF), preventing damaging back-current flow through the device. This feature is fully specified and tested per JEDEC standards for hot-swap and modular system applications.
What package type and footprint does the 74FCT16374TPVCTG4 use?
The 74FCT16374TPVCTG4 uses a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 0.025-inch lead pitch, compliant with JEDEC MO-118. Its mechanical drawing is DL, and it measures 18.54 mm × 7.59 mm × 2.39 mm. The package is RoHS-compliant with green (Pb-free, no Sb/Br) finish and CU NIPDAU lead finish.
How does the 74FCT16374TPVCTG4 differ from the 74FCT162374TPVCTG4 in output driver design?
The 74FCT16374TPVCTG4 uses asymmetrical 64 mA sink / 32 mA source drivers optimized for driving heavy capacitive loads like backplanes, while the 74FCT162374TPVCTG4 employs balanced 24 mA drivers with integrated current-limiting resistors to minimize ground bounce (<0.6 V) and undershoot on transmission lines-making it better suited for impedance-controlled routing.
Is the 74FCT16374TPVCTG4 pin-compatible with other members of the CY74FCT16374T family?
Yes, the 74FCT16374TPVCTG4 is fully pin-compatible with all speed grades (T, AT, CT) and package variants (SSOP/PVCT, TSSOP/PACT) of the CY74FCT16374T family, including CY74FCT16374ATPVCTG4 and CY74FCT16374CTPVCTG4. All share identical pin configuration, electrical interface, and functional behavior-only propagation delay and dynamic current specs differ.
