NXP Semiconductors 74LVC1G79GF,132

Overview

74LVC1G79GF,132 from Nexperia is a single positive-edge-triggered D-type flip-flop in XSON6 (SOT886) package, operating from 1.65 V to 5.5 V supply. It stores data at the D-input on LOW-to-HIGH clock transitions, features ±24 mA output drive at 3.0 V, Schmitt-trigger inputs for noise immunity, and IOFF circuitry enabling partial power-down mode. It is used in level translation between 3.3 V and 5 V logic domains in compact timing control circuits.

For engineers reviewing the 74LVC1G79GF,132 datasheet, 74LVC1G79GF,132 pinout, 74LVC1G79GF,132 application, or 74LVC1G79GF,132 equivalent, key selection criteria include propagation delay (as low as 0.5 ns at 5.5 V), set-up/hold time compliance across voltage ranges, IOFF-enabled bus isolation during power sequencing, and compatibility with mixed-voltage I/O interfaces in space-constrained embedded systems.

Technical Context

This device implements a synchronous edge-triggered storage element with transparent input-to-output behavior only on the rising edge of CP. Its Schmitt-trigger inputs accept slow-rising signals and tolerate input voltages up to 5.5 V regardless of VCC, enabling robust interfacing with legacy TTL or higher-voltage peripherals.

The IOFF circuit disables outputs when VCC = 0 V, preventing backflow current during partial power-down - a critical requirement for hot-swap and multi-rail power management. All static and dynamic parameters are fully specified over –40 °C to +125 °C, supporting automotive and industrial temperature-grade operation.

FAQ

What is the maximum clock frequency supported by the 74LVC1G79GF,132?

The 74LVC1G79GF,132 supports a maximum clock frequency of 500 MHz at VCC = 4.5–5.5 V and Tamb = 25 °C, with guaranteed minimum fmax of 200 MHz across the full –40 °C to +125 °C operating range. This is validated by tW (clock pulse width) ≥ 2.0 ns and tpd ≤ 5.0 ns under worst-case conditions.

Does the 74LVC1G79GF,132 require external pull-up or pull-down resistors on its inputs?

No external pull-up or pull-down resistors are required. The device features Schmitt-trigger inputs with built-in hysteresis, ensuring clean switching even with slow or noisy signals. Input leakage current is limited to ±1 μA, and VIH/VIL thresholds scale with VCC, eliminating ambiguity in undefined states.

Can the 74LVC1G79GF,132 be used in a 1.8 V system with 3.3 V inputs?

Yes. Inputs tolerate up to 5.5 V regardless of VCC, so 3.3 V signals may safely drive D or CP when VCC = 1.8 V. Output VOH/VOL remain compliant with 1.8 V logic thresholds (VIH ≥ 1.2 V, VIL ≤ 0.45 V), enabling bidirectional voltage translation without external components.

How does the IOFF feature behave during power-down sequences?

When VCC drops to 0 V, the IOFF circuit actively disables both Q output and internal input buffers, limiting I/O leakage to ±2 μA maximum. This prevents back-current flow into powered-down sections - a critical capability for systems requiring controlled power sequencing, such as automotive domain controllers with independent rail management.
