Nexperia USA Inc. 74LVC1G79GM,132

Overview

74LVC1G79GM,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 on LOW-to-HIGH clock transitions with 0.5 ns minimum pulse width, ±24 mA output drive at 3.0 V, and supports mixed-voltage interfacing between 3.3 V and 5 V systems. Used for synchronous data latching in compact timing-critical logic paths.

For engineers reviewing the 74LVC1G79GM,132 datasheet, 74LVC1G79GM,132 pinout, 74LVC1G79GM,132 application, or 74LVC1G79GM,132 equivalent, key selection criteria include edge-triggered storage behavior, IOFF-enabled partial power-down capability, Schmitt-trigger input tolerance for slow edges, and verified operation across –40 °C to +125 °C.

Technical Context

This device implements a basic synchronous D-flip-flop function with no internal reset or preset. Its positive-edge triggering relies on precise setup (≥0.5 ns at VCC = 3.0 V) and hold (≥–0.3 ns) timing relative to the CP input transition. The IOFF circuit disables outputs during power-down to prevent backflow current when VCC = 0 V.

Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising signals up to 20 ns/V (VCC = 1.65 V). Input voltage tolerance extends to 5.5 V regardless of VCC, allowing direct connection to higher-voltage logic without level shifters.

FAQ

What is the minimum clock pulse width required for reliable operation?

The minimum CP pulse width is 0.5 ns at VCC = 3.0 V and 2.0 ns at VCC = 1.65 V, as specified in Table 8. This ensures proper internal state capture and avoids metastability. Pulse widths below these values may result in undefined output behavior or failure to latch data.

Can the 74LVC1G79GM,132 interface directly with 5 V TTL outputs?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, and its VIH threshold is 0.7 × VCC (e.g., 2.1 V at VCC = 3.0 V), making it compatible with standard 5 V TTL output levels. No external level shifter is needed.

Does the n.c. pin on the XSON6 package require any PCB layout treatment?

Pin 5 is internally unconnected and must remain electrically floating. It should not be soldered to ground or power planes. Standard IPC-7351B land pattern guidelines apply; no thermal relief or stitching is required for this terminal.

How does the IOFF feature behave during power sequencing?

When VCC drops to 0 V, the IOFF circuit actively disables both Q output and internal input buffers, limiting leakage to ≤±2 μA even if D or CP pins are held at 5.5 V. This prevents reverse current flow into the powered-down IC, protecting upstream drivers and adjacent rails.
