NXP Semiconductors 74LVC16374ADGG,112

Overview

74LVC16374ADGG,112 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), and Schmitt-trigger inputs for noise immunity. Used in bus interface buffering and data latching in mixed-voltage industrial control systems.

For engineers reviewing the 74LVC16374ADGG,112 datasheet, 74LVC16374ADGG,112 pinout, 74LVC16374ADGG,112 application, or 74LVC16374ADGG,112 equivalent, this device supports translation between 3.3 V and 5 V logic domains, delivers sub-5 ns propagation delay at 3.3 V, maintains high-impedance outputs during power-down via IOFF, and operates reliably from –40 °C to +125 °C.

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 (1CP or 2CP) while meeting set-up (1.9 ns min at 3.3 V) and hold (1.5 ns min) timing requirements.

Inputs tolerate up to 5.5 V regardless of VCC level (1.2–3.6 V), enabling seamless interfacing with legacy 5 V TTL or CMOS drivers. The IOFF circuit actively disables outputs when VCC = 0 V, preventing backflow current during partial power-down sequences in multi-rail systems.

FAQ

Is 74LVC16374ADGG,112 pin-compatible with 74LVCH16374ADGG,118?

No - although both use the TSSOP48 package and share identical pin assignments, the 74LVCH16374ADGG,118 includes bus hold circuitry on data inputs, which alters input leakage behavior and may cause unexpected DC loading on externally driven lines. Physical compatibility does not guarantee functional interchangeability without board-level validation.

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

At VCC = 1.8 V (within JESD8-7A range), the maximum guaranteed clock frequency is 80 MHz, derived from the 13.5 ns maximum propagation delay (tpd) and 5.0 ns minimum clock pulse width (tW) specified in Table 7. This ensures reliable setup/hold margin for synchronous data capture in low-power sensor hubs.

Can 74LVC16374ADGG,112 drive standard 50 Ω transmission lines directly?

No - the device is rated for capacitive loads up to 50 pF (per output) and is not designed for 50 Ω impedance matching. Driving controlled-impedance lines requires external series termination (e.g., 33 Ω resistor) to suppress reflections; typical fan-out is 10 LVTTL loads, not transmission-line routing.

Does the IOFF feature activate automatically when VCC drops below a threshold?

Yes - IOFF is inherent to the silicon design and activates whenever VCC is near 0 V (typically < 0.2 V), regardless of input voltage or OE state. It does not require external control or biasing; the output transistors are physically disabled, limiting OFF-state leakage to ±10 μA maximum per pin at 5.5 V applied.
