Product details
Overview
CY74FCT162374TPVC from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit sections, designed for high-speed bus buffering in industrial systems. It features balanced 24 mA output drivers, 10 ns max propagation delay (CLK to O), Ioff partial-power-down support, and operates at 5V ±10% across −40°C to +85°C. It is used in backplane interface logic where low ground bounce and transmission-line drive capability are critical.
For engineers reviewing the CY74FCT162374TPVC datasheet, CY74FCT162374TPVC pinout, CY74FCT162374TPVC application, or CY74FCT162374TPVC equivalent, key selection criteria include its 24 mA balanced drive strength, <0.6 V typical ground bounce (VOLP), flow-through pinout for PCB layout simplification, and SSOP-48 packaging compatible with industrial temperature and RoHS requirements.
Technical Context
The CY74FCT162374TPVC implements two independent 8-bit registers sharing common clock (CLK) and output-enable (OE) inputs, enabling flexible 8-bit or 16-bit operation. Its edge-rate controlled outputs reduce system switching noise and eliminate need for external termination resistors on transmission lines.
It integrates Ioff circuitry that disables outputs during power-down to prevent current backflow, and uses current-limiting resistors within 24 mA output drivers to minimize undershoot and ground bounce-critical for signal integrity in high-density digital systems.

FAQ
What is the maximum clock frequency supported by the CY74FCT162374TPVC?
The CY74FCT162374TPVC does not specify a maximum clock frequency directly, but its 10 ns maximum propagation delay (tPLH/tPHL) and 5 ns minimum clock pulse width (tW) imply reliable operation up to approximately 100 MHz in well-designed systems with controlled trace impedance and proper termination. Actual usable frequency depends on board layout, load capacitance, and timing margin requirements in the target application.
Does the CY74FCT162374TPVC support hot-swap or partial-power-down operation?
Yes, the CY74FCT162374TPVC includes Ioff circuitry that actively disables outputs when VCC = 0 V, preventing damaging current backflow during hot-swap events or partial-power-down sequences. This feature is fully specified over the industrial temperature range and requires no external components-making the CY74FCT162374TPVC suitable for modular systems with live-insertion capability.

The CY74FCT162374TPVC provides balanced ±24 mA output drive with integrated current-limiting resistors, resulting in low ground bounce (<0.6 V). In contrast, the CY74FCT16374TPVC delivers asymmetric 64 mA sink / 32 mA source drive without current limiting, yielding higher ground bounce (<1.0 V) and requiring external termination for clean signal edges-making the CY74FCT162374TPVC preferable for noise-sensitive transmission-line applications.
Is the CY74FCT162374TPVC pin-compatible with other devices in the FCT16x374 family?
Yes, the CY74FCT162374TPVC shares identical pinout, package (SSOP-48), and functional block diagram with CY74FCT16374TPVC and CY74FCT162374ATPVC/CY74FCT162374CTPVC. All variants use the same flow-through arrangement, power/ground pin distribution, and OE/CLK/D/O terminal assignments-enabling drop-in replacement within the same speed grade and drive-class family.
What is the meaning of "PVCT" suffix in CY74FCT162374TPVC?
The "PVCT" suffix in CY74FCT162374TPVC indicates a 48-pin SSOP (Shrink Small Outline Package) with tape-and-reel packaging (T), green RoHS-compliant finish (no Sb/Br), and CU NIPDAU lead finish.
