Nexperia USA Inc. 74LVC16374ADGG,118

Overview

74LVC16374ADGG,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 level translation between 3.3 V and 5 V domains in industrial control backplanes.

For engineers reviewing the 74LVC16374ADGG,118 datasheet, 74LVC16374ADGG,118 pinout, 74LVC16374ADGG,118 application, or 74LVC16374ADGG,118 equivalent, this device supports mixed-voltage system interfacing, high-speed data latching with sub-7 ns propagation delay at 3.3 V, and robust ESD immunity (HBM >2000 V) for reliable operation in noisy industrial environments.

Technical Context

This device implements two independent 8-bit D-flip-flop banks, each with dedicated clock and output enable, enabling flexible partitioning as either one 16-bit or two synchronized 8-bit registers. The IOFF circuit actively disables outputs when VCC = 0 V, preventing backflow current during partial power-down sequences.

All inputs include Schmitt-trigger action for noise immunity and compatibility with slow-rising signals, while bus-hold functionality (on 74LVCH variant only) is absent in the 74LVC16374A version - confirmed by pin description table and feature list exclusions in Section 2.

FAQ

Is the 74LVC16374ADGG,118 pin-compatible with the 74LVCH16374ADGG,118?

Yes - both devices share identical TSSOP48 (SOT362-1) pinout, electrical timing, and functional behavior. The sole difference is that the 74LVCH variant adds bus-hold circuitry on data inputs, which does not affect pin assignment or signal routing. No PCB redesign is needed when substituting between them.

What is the maximum clock frequency supported at 1.8 V supply?

At VCC = 1.8 V, the device supports up to 100 MHz operation, as derived from the fmax specification of 100 MHz minimum over -40 °C to +85 °C (Table 7). This is validated by tW (clock pulse width) ≥ 5.0 ns and tpd ≤ 13.5 ns under those conditions.

Does this device support hot-swap insertion while other system rails remain active?

Yes - the IOFF circuit ensures outputs enter high-impedance state when VCC = 0 V, preventing current backflow from live 5 V or 3.3 V buses into the unpowered IC. This capability is explicitly verified in the datasheet's "partial power down" section and limiting values table.

Can the 1CP and 2CP inputs be tied together for single 16-bit operation?

Yes - connecting 1CP and 2CP enables simultaneous latching across all 16 bits. The functional diagram and truth table confirm identical behavior per bank under shared clock; no timing penalty or functional restriction applies, and setup/hold requirements remain unchanged per input.
