Nexperia USA Inc. 74LVC1G79GS,132

Overview

74LVC1G79GS,132 from Nexperia is a single positive-edge-triggered D-type flip-flop in XSON6 (SOT1202) package, operating from 1.65 V to 5.5 V supply, with ±24 mA output drive at 3.0 V, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It functions as a synchronous data latch in clock-domain interfacing, level translation, and metastability mitigation circuits - e.g., synchronizing asynchronous control signals in low-power microcontroller I/O expansion.

For engineers reviewing the 74LVC1G79GS,132 datasheet, 74LVC1G79GS,132 pinout, 74LVC1G79GS,132 application, or 74LVC1G79GS,132 equivalent, this device supports mixed-voltage (3.3 V/5 V) signal conditioning, offers guaranteed setup/hold timing down to 0.5 ns at 5 V, and delivers rail-to-rail CMOS-compatible outputs with sub-1 μA ICC quiescent current - critical for battery-powered edge nodes and space-constrained PCB layouts.

Technical Context

This flip-flop implements a master-slave D-latch architecture synchronized to the rising edge of CP, storing D-input state only when setup (tsu ≥ 0.5 ns @ 5 V) and hold (th ≥ +0.5 ns @ 5 V) constraints are met. Its Schmitt-trigger inputs accept slow-rising signals (Δt/ΔV ≤ 10 ns/V above 2.7 V), enabling robust operation with noisy or RC-filtered clocks.

The IOFF circuit actively disables outputs during VCC = 0 V, blocking backflow current from live buses into powered-down subsystems - a key requirement for hot-swap and partial-power-down systems. Input overvoltage tolerance to 5.5 V allows direct connection to 5 V logic even when VCC = 1.8 V, eliminating external level shifters in mixed-supply domains.

FAQ

What is the maximum clock frequency supported by the 74LVC1G79GS,132?

The device supports up to 500 MHz maximum clock frequency at VCC = 4.5 V to 5.5 V, as verified by fmax testing in the datasheet (Table 8). At lower voltages (e.g., 1.8 V), fmax drops to 160 MHz due to increased propagation delay. This rating assumes proper load conditions (CL ≤ 30 pF, RL = 500 Ω) and meets JEDEC JESD8-7 compliance.

Does the 74LVC1G79GS,132 require external pull-up or pull-down resistors on its inputs?

No - Schmitt-trigger inputs provide inherent hysteresis and noise immunity, eliminating the need for external biasing resistors. However, unused inputs (e.g., if D is statically driven) must still be tied to VCC or GND to prevent floating states and excessive ICC. The n.c. pin (Pin 5) must remain unconnected.

Can the 74LVC1G79GS,132 be used in a 5 V system with a 3.3 V supply rail?

Yes - its overvoltage-tolerant inputs accept 5.5 V signals regardless of VCC level. When VCC = 3.3 V, the device correctly interprets 5 V logic-high inputs and outputs 3.3 V-compatible levels, enabling seamless level translation without external components - confirmed by VIH/VIL specifications across all VCC ranges.

How does the IOFF feature behave during power sequencing?

When VCC drops below 0.2 V, the IOFF circuit automatically places Q and D outputs in high-impedance state, blocking current flow between powered and unpowered sections. This behavior is tested and guaranteed down to −40 °C and holds for up to ±2 μA leakage - critical for systems with staggered power rails or hot-swap capability.
