Nexperia USA Inc. 74LVT162374DGG,112

Overview

74LVT162374DGG,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 interface applications.

For engineers reviewing the 74LVT162374DGG,112 datasheet, 74LVT162374DGG,112 pinout, 74LVT162374DGG,112 application, or 74LVT162374DGG,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 packaging optimized for 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, enabling synchronous latching and 3-state bus control. Its architecture integrates series 30 Ω resistors in both HIGH and LOW output states to suppress transmission-line reflections without external components.

Input compatibility spans 3.3 V and 5 V systems via TTL-level thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), while bus-hold circuitry maintains stable logic states on unused D inputs. Power-up reset and 3-state initialization ensure deterministic behavior during system boot and hot-swap scenarios.

FAQ

Does the 74LVT162374DGG,112 support hot-plug operation?

Yes. The device supports live insertion and extraction per its datasheet specification, enabled by power-up 3-state behavior, bus-hold inputs, and ESD protection rated to HBM >2000 V and CDM >1000 V. This ensures safe connection/disconnection in powered-backplane systems without disrupting adjacent logic.

Can the 74LVT162374DGG,112 drive 5 V-tolerant inputs directly?

Yes. Its outputs swing rail-to-rail (VOH ≥ 2.0 V at IOH = −12 mA, VOL ≤ 0.8 V at IOL = 12 mA) and inputs accept VI up to 5.5 V, allowing direct interface with 5 V TTL and CMOS loads without level-shifting circuitry-verified under recommended operating conditions.

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

The 30 Ω resistor is integrated into both HIGH and LOW output paths to match typical PCB trace impedance, suppressing reflections and overshoot/undershoot on transmission lines. This eliminates the need for 16 external series resistors while maintaining signal fidelity in memory address and clock routing.

How does bus-hold functionality behave during power-up?

Bus-hold remains active during power-up sequences, retaining the last valid logic state on D inputs even before VCC reaches full regulation. This prevents metastability or undefined outputs during ramp-up, complementing the power-up 3-state feature that holds Q outputs in high-Z until stable operation is achieved.
