Product details
Overview
74FCT162374ATPVCG4 from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, balanced 24 mA output drivers, 6.5 ns max propagation delay (CLK to O), and Ioff partial-power-down support. It operates at 5V ±10% across −40°C to +85°C and is optimized for low-noise transmission-line driving in high-speed bus interfaces.
For engineers reviewing the 74FCT162374ATPVCG4 datasheet, 74FCT162374ATPVCG4 pinout, 74FCT162374ATPVCG4 application, or 74FCT162374ATPVCG4 equivalent, this device delivers precise timing control, reduced ground bounce (<0.6 V), flow-through pinout for simplified PCB routing, and industrial-grade reliability in SSOP packaging.
Technical Context
The 74FCT162374ATPVCG4 implements two independent 8-bit registers sharing common clock and output-enable inputs, enabling flexible data latching in parallel bus architectures. Its balanced 24 mA drivers incorporate internal current-limiting resistors to minimize undershoot and eliminate need for external termination on controlled-impedance lines.
Designed for partial-power-down operation, the Ioff circuitry disables outputs when VCC = 0 V, preventing backflow current. Edge-rate control circuitry ensures <250 ps typical output skew and significantly improved noise immunity versus standard FCT logic.

FAQ
What is the maximum clock frequency supported by the 74FCT162374ATPVCG4?
The 74FCT162374ATPVCG4 has a minimum clock pulse width of 5.0 ns (HIGH or LOW), supporting guaranteed operation up to 100 MHz. With typical propagation delay of ~4 ns and tight output skew, it reliably handles 125–150 MHz in well-designed systems with proper termination and layout. The 74FCT162374ATPVCG4 does not specify a maximum frequency limit but is characterized for timing up to its 6.5 ns worst-case tPLH/tPHL.
Does the 74FCT162374ATPVCG4 support hot-swap or partial-power-down operation?
Yes-the 74FCT162374ATPVCG4 integrates Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during hot-insertion or mixed-rail power sequencing. This feature is fully specified over −40°C to +85°C and verified per JEDEC JESD78, making the 74FCT162374ATPVCG4 suitable for modular backplane and field-replaceable unit designs.
What is the meaning of "G4" in the part number 74FCT162374ATPVCG4?
The "G4" suffix in 74FCT162374ATPVCG4 indicates Green (RoHS-compliant) packaging with no bromine or antimony-based flame retardants, per TI's eco-plan classification. It confirms CU NIPDAU lead finish, Level-1 MSL rating (260°C peak reflow), and compliance with EU RoHS Directive 2011/65/EU. The 74FCT162374ATPVCG4 is not lead-free exempt and contains no Pb, Sb, or Br above threshold limits.
Can the 74FCT162374ATPVCG4 be used as two independent 8-bit registers?
Yes-the 74FCT162374ATPVCG4 contains two functionally independent 8-bit registers (labeled "1" and "2") with separate clock (1CLK/2CLK) and output-enable (1OE/2OE) inputs. Each register latches its respective D-inputs on the rising edge of its clock and drives outputs only when its OE is low. This allows concurrent operation at different clock rates or selective bus partitioning without inter-register coupling.
What is the recommended decoupling for the 74FCT162374ATPVCG4 in high-speed applications?
TI recommends one 100 nF X7R ceramic capacitor per VCC–GND pair (pins 24/25 and 47/48), placed within 3 mm of each pair, plus a bulk 4.7 µF tantalum or polymer capacitor near the SSOP footprint. The 74FCT162374ATPVCG4's dual power/ground pairs are designed to minimize simultaneous switching noise-decoupling must target both pairs independently to maintain <0.6 V ground bounce under full 24 mA switching.
