Nexperia USA Inc. 74LVT162374DGG,518

Overview

74LVT162374DGG,518 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 operates across -40 °C to +85 °C, delivers ±12 mA drive strength, and supports 5 V-tolerant TTL-level inputs/outputs-enabling direct interfacing with legacy 5 V buses. It serves as a high-noise-immunity memory address driver or clock distribution register in industrial control backplanes.

For engineers reviewing the 74LVT162374DGG,518 datasheet, 74LVT162374DGG,518 pinout, 74LVT162374DGG,518 application, or 74LVT162374DGG,518 equivalent, key selection criteria include its dual 8-bit/16-bit configurable operation, bus-hold inputs eliminating external pull-ups, power-up 3-state behavior, and guaranteed 150 MHz maximum clock frequency at 3.3 V.

Technical Context

This BiCMOS device implements two independent 8-bit D-type flip-flop sections (1CP/1OE and 2CP/2OE), each with synchronous positive-edge clocking and asynchronous 3-state control. Its internal 30 Ω series output resistance is fixed per pin and active in both HIGH and LOW states-reducing ringing and EMI without requiring external termination.

The device features bus-hold circuitry on all data inputs (1D0–1D7, 2D0–2D7), maintaining valid logic states when inputs float, and supports live insertion/extraction. Power-up reset ensures outputs enter high-impedance state before VCC stabilizes, preventing bus contention during system boot.

FAQ

Does the 74LVT162374DGG,518 require external pull-up resistors on unused data inputs?

No. All data inputs (1D0–1D7, 2D0–2D7) feature integrated bus-hold circuitry that maintains the last-valid logic state when left floating. This eliminates the need for external pull-up or pull-down resistors, simplifying PCB layout and reducing BOM cost-confirmed in Section 2 and Table 6 of the Rev. 6 datasheet.

Can the 74LVT162374DGG,518 safely interface with a 5 V microcontroller's address bus?

Yes. Its inputs tolerate up to 5.5 V and outputs drive 5 V-tolerant loads, enabling direct connection to 5 V systems without level-shifting components. The device maintains 3.3 V logic thresholds internally while meeting TTL switching levels-verified in Tables 5 and 6 under Recommended Operating Conditions and Static Characteristics.

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

The 30 Ω resistor is placed in series with every output (1Q0–1Q7, 2Q0–2Q7) to match typical PCB trace impedance and dampen signal reflections. This reduces ringing and EMI in high-speed bus applications like memory addressing and clock distribution-explicitly stated in Section 1 and Figure 4 of the datasheet.

Is the 74LVT162374DGG,518 suitable for hot-swap applications in modular backplanes?

Yes. It supports live insertion and extraction per Section 2, and its power-up 3-state behavior ensures outputs remain high-impedance until VCC stabilizes-preventing bus contention during module insertion. Latch-up protection exceeds 500 mA (JESD78B Class II), confirming robustness in dynamic system environments.
