Nexperia USA Inc. 74LVT16374ADL,112

Overview

74LVT16374ADL,112 from Nexperia is a 3.3 V 16-bit edge-triggered D-type flip-flop with 3-state outputs in TSSOP48 package, featuring dual independent 8-bit sections (1CP/1OE and 2CP/2OE), 150 MHz maximum clock frequency, and ±64 mA output drive capability. It operates across -40 °C to +85 °C and supports direct TTL-level interfacing in high-speed data bus applications.

For engineers reviewing the 74LVT16374ADL,112 datasheet, 74LVT16374ADL,112 pinout, 74LVT16374ADL,112 application, or 74LVT16374ADL,112 equivalent, key selection considerations include dual-clock timing control, bus-hold inputs (LVTH variant only), overvoltage-tolerant 5.5 V inputs, and precise set-up/hold time requirements (0.8 ns / 0.1 ns at 3.3 V).

Technical Context

This device implements two independent 8-bit D-type flip-flop banks, each with dedicated clock (1CP/2CP) and output enable (1OE/2OE) inputs, enabling flexible partitioning as either one 16-bit or two synchronized 8-bit registers. The LOW-to-HIGH clock transition triggers synchronous data capture, while OE inputs independently place corresponding Q outputs into high-impedance state without affecting internal register state.

It uses BiCMOS process technology to achieve high-speed operation (tPLH/tPHL ≤ 3.0 ns at 3.3 V) and robust output drive (+64 mA sink, –32 mA source), with input clamping, IOFF power-down protection, and bus-hold circuitry on data inputs-though bus-hold is confirmed only for the 74LVTH16374A variant, not the base 74LVT16374A.

FAQ

What is the difference between 74LVT16374ADL,112 and 74LVTH16374ADGG?

The 74LVTH16374ADGG includes bus-hold circuitry on all data inputs, eliminating the need for external pull-up resistors on unused or floating inputs. The 74LVT16374ADL,112 lacks this feature but shares identical timing, drive strength, pinout, and overvoltage tolerance. Both use the same TSSOP48 package and operate across –40 °C to +85 °C.

Does 74LVT16374ADL,112 support hot insertion?

Yes - the device supports live insertion and extraction due to its IOFF circuitry, which disables current flow through powered-off outputs, and its power-up 3-state behavior that holds outputs in high-impedance until VCC stabilizes above threshold. This prevents bus contention during hot-swap operations in modular backplane systems.

Can 74LVT16374ADL,112 interface directly with 5 V TTL logic?

Yes - its inputs tolerate up to +5.5 V regardless of VCC level, and its outputs swing rail-to-rail (VOL ≈ 0.4 V, VOH ≈ VCC – 0.2 V at full load), meeting TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) when VCC = 3.3 V. No level-shifting components are required for bidirectional 5 V ↔ 3.3 V interfacing.

What is the minimum pulse width required on 1CP/2CP inputs?

The minimum clock pulse width is 3.0 ns at VCC = 2.7 V and 1.5 ns at VCC = 3.3 V, per the datasheet's tW specification. This defines the shortest HIGH or LOW duration the clock must maintain to ensure reliable edge detection and data capture - critical for designing clock distribution networks with minimal jitter and duty-cycle distortion.
