NXP Semiconductors 74AUP1G374GF,132

Overview

74AUP1G374GF,132 from Nexperia is a single low-power D-type flip-flop with positive-edge clock trigger and 3-state output enable (active LOW). It operates across 0.8 V to 3.6 V supply, delivers ≤0.9 μA max ICC at 25 °C, supports −40 °C to +125 °C ambient, and features IOFF circuitry for partial power-down protection in battery-powered IoT sensor nodes.

For engineers reviewing the 74AUP1G374GF,132 datasheet, 74AUP1G374GF,132 pinout, 74AUP1G374GF,132 application, or 74AUP1G374GF,132 equivalent, key selection criteria include its ultra-low static current, Schmitt-trigger inputs for noise immunity on slow-rising control signals, 3-state bus isolation capability, and compatibility with mixed-voltage logic domains in portable embedded systems.

Technical Context

This device implements a synchronous edge-triggered storage element with independent output enable control - enabling precise timing of data latching while allowing dynamic bus contention avoidance. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during power sequencing.

Schmitt-trigger inputs tolerate input rise/fall times up to 200 ns/V, making it robust against noisy or slew-limited control lines. The flip-flop's propagation delay ranges from 1.2 ns (VCC = 3.3 V, CL = 5 pF) to 40.8 ns (VCC = 0.8 V, CL = 30 pF), supporting both high-speed register transfer and low-power wake-up synchronization.

FAQ

What is the maximum clock frequency supported by the 74AUP1G374GF,132?

The device achieves up to 619 MHz maximum clock frequency at VCC = 3.3 V and CL = 5 pF, dropping to 309 MHz at CL = 30 pF. At lower voltages, fmax scales down - e.g., 481 MHz at VCC = 3.0 V (CL = 5 pF) and 181 MHz at VCC = 1.2 V (CL = 5 pF). These values are measured under specified test conditions per Figure 7 and Table 8.

Does the 74AUP1G374GF,132 support partial power-down when VCC is disconnected?

Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting OFF-state leakage to ±0.75 μA. This prevents back-current flow through the device when connected to a live bus, satisfying IEC 61000-4-2 and automotive hot-swap requirements without external protection diodes.

How does the Schmitt-trigger input improve noise immunity in real-world applications?

Schmitt-trigger action provides ~30 % hysteresis (e.g., VIH ≈ 0.65×VCC, VIL ≈ 0.35×VCC at 1.8 V), rejecting noise spikes and slow-rising signals that would cause multiple transitions on standard CMOS inputs. This eliminates need for external RC filters on mechanical switch inputs or long PCB traces in industrial control panels.

Can the 74AUP1G374GF,132 operate reliably at 0.8 V supply voltage?

Yes - it is fully characterized from 0.8 V to 3.6 V, with guaranteed tpd ≤ 40.8 ns (CL = 30 pF), tsu ≥ 0.5 ns, and ICC ≤ 1.4 μA at −40 °C to +125 °C. At 0.8 V, VOH remains ≥ 0.70×VCC and VOL ≤ 0.30×VCC, ensuring interoperability with other 0.8 V logic families in ultra-low-power SoC subsystems.
