Nexperia USA Inc. 74LVC16374ADL,118

Overview

74LVC16374ADL,118 from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual independent 8-bit sections, 3-state outputs, 5 V-tolerant inputs, and operation across 1.2 V to 3.6 V supply. It features two clocks (1CP/2CP), two output enables (1OE/2OE), Schmitt-trigger inputs, and IOFF partial power-down protection. Used in bus interface buffering and data latching in mixed-voltage industrial control systems.

For engineers reviewing the 74LVC16374ADL,118 datasheet, 74LVC16374ADL,118 pinout, 74LVC16374ADL,118 application, or 74LVC16374ADL,118 equivalent, this device supports voltage translation between 3.3 V and 5 V domains, delivers sub-5 ns propagation delay at 3.3 V, maintains high-impedance outputs during power-down, and provides bus hold on data inputs (LVCH variant).

Technical Context

This device implements two independent 8-bit positive-edge-triggered D flip-flop banks, each with dedicated clock and output enable. Each bank latches input data on the LOW-to-HIGH transition of its respective clock while meeting set-up (1.9 ns min at 3.3 V) and hold (1.5 ns min) timing requirements.

Its IOFF circuit disables outputs when VCC = 0 V, preventing backflow current; Schmitt-trigger inputs tolerate slow edges; and 5.5 V-tolerant inputs allow direct interfacing with 5 V logic while powered from 1.2–3.6 V supplies.

FAQ

Is 74LVC16374ADL,118 pin-compatible with 74LVCH16374ADGG?

Yes - both devices use identical TSSOP48 (SOT362-1) packaging and share identical pin assignments, electrical timing, and functional behavior. The only difference is that the LVCH variant includes bus hold circuitry on data inputs, while the LVC version does not. No PCB redesign is needed for substitution.

What is the maximum clock frequency supported at 2.5 V supply?

At VCC = 2.5 V, the device supports a maximum clock frequency of 100 MHz (minimum fmax = 100 MHz over −40 °C to +125 °C per Table 7). This is derived from the 10 ns maximum propagation delay (tpd) and 3 ns minimum pulse width (tW) specified for the 2.3 V to 2.7 V range.

Does 74LVC16374ADL,118 support partial power-down with IOFF?

Yes - the IOFF circuit activates when VCC = 0 V, forcing all outputs into high-impedance state regardless of OE or clock states. This prevents back-current flow from live buses into a powered-down device, satisfying JEDEC JESD78 Class II latch-up immunity requirements.

Can inputs be driven by 5 V TTL logic while VCC = 1.8 V?

Yes - all inputs are 5.5 V tolerant and fully compatible with 5 V TTL output levels (VOH ≈ 3.5 V, VOL ≈ 0.4 V) even when VCC is as low as 1.2 V. Input thresholds scale with VCC (e.g., VIH = 0.65×VCC at 1.65–1.95 V), ensuring correct logic interpretation across the full supply range.
