Nexperia USA Inc. 74LVT162374DL,112

Overview

74LVT162374DL,112 from Nexperia is a 3.3 V, 16-bit edge-triggered D-type flip-flop with integrated 30 Ω series output termination resistors and non-inverting 3-state outputs. It functions as two independent 8-bit registers or one unified 16-bit register, clocked on the rising edge of CP inputs, and operates across -40 °C to +85 °C for memory address drivers, clock distribution, and bus transceiver applications.

For engineers reviewing the 74LVT162374DL,112 datasheet, 74LVT162374DL,112 pinout, 74LVT162374DL,112 application, or 74LVT162374DL,112 equivalent, key selection criteria include its 30 Ω on-die termination, ±12 mA drive strength, TTL-compatible I/O, bus-hold inputs eliminating external pull-ups, and TSSOP48 package compatibility with high-density PCB layouts.

Technical Context

This BiCMOS device implements dual 8-bit D-flip-flop banks, each with independent clock (1CP/2CP) and output enable (1OE/2OE) controls. Its architecture supports synchronous loading on the rising edge of CP while maintaining data integrity via bus-hold circuitry on all D inputs.

Each output integrates 30 Ω series resistance in both HIGH and LOW states-reducing signal reflections and line noise without requiring external termination. The device interfaces seamlessly with 5 V systems while operating at 3.3 V VCC, and features power-up 3-state and reset behavior to prevent bus contention during power sequencing.

FAQ

Does the 74LVT162374DL,112 require external pull-up resistors on unused D inputs?

No. All D inputs feature integrated bus-hold circuitry that maintains the last valid logic state with ±75 μA to ±135 μA holding current, eliminating the need for external pull-up or pull-down resistors and reducing BOM count and board space.

Can the 74LVT162374DL,112 safely interface with a 5 V bus while powered at 3.3 V?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC level, and outputs drive 5 V-tolerant loads with ±12 mA current. No level-shifting circuitry is required, enabling direct connection to legacy 5 V buses in mixed-voltage systems.

What is the purpose of the 30 Ω series resistance on each output?

The 30 Ω resistor is monolithically integrated into each output path to match typical PCB trace impedance, suppressing signal reflections, overshoot, and EMI in high-speed memory and clock buses-removing the need for 16 discrete termination resistors and improving layout reproducibility.

How does the power-up behavior prevent bus contention?

At power-on, all outputs enter a high-impedance (3-state) condition before VCC stabilizes, and internal reset ensures outputs remain inactive until supply reaches valid operating voltage-eliminating glitches or short-duration contention on shared data or address buses during power sequencing.
