Texas Instruments SN74AUP1G80DCKRG4

Overview

SN74AUP1G80DCKRG4 from Texas Instruments is a single positive-edge-triggered D-type flip-flop in SC70-5 package, operating from 0.8 V to 3.6 V supply, with 4.4 ns max propagation delay at 3.3 V, 1.5 pF typical input capacitance, and Ioff support for partial-power-down mode. It serves as a low-power clocked data latch in battery-powered signal conditioning and timing control circuits.

For engineers reviewing the SN74AUP1G80DCKRG4 datasheet, SN74AUP1G80DCKRG4 pinout, SN74AUP1G80DCKRG4 application, or SN74AUP1G80DCKRG4 equivalent, key selection criteria include its ultra-low ICC (0.9 µA max), 3.6-V I/O tolerance for mixed-voltage interfacing, Schmitt-trigger input hysteresis (250 mV typ), and validated operation across –40°C to +85°C industrial temperature range.

Technical Context

The SN74AUP1G80DCKRG4 implements a synchronous edge-triggered storage element with voltage-level clock detection-unaffected by clock rise time-enabling robust timing in noisy or slow-ramping clock domains. Its balanced CMOS push-pull output drives up to ±4 mA at 3 V while maintaining low dynamic power (Cpd = 4.3 pF typ).

Designed for partial-power-down systems, the device features Ioff circuitry that disables outputs and limits leakage to ≤0.6 µA when VCC = 0 V, preventing backflow current. Input hysteresis (Vhys = 250 mV typ at 3.3 V) improves noise immunity for slow-transition signals, and 3.6-V I/O tolerance allows safe interfacing with higher-voltage logic without level shifters.

FAQ

What is the minimum supply voltage for reliable operation of SN74AUP1G80DCKRG4?

The SN74AUP1G80DCKRG4 is fully specified from 0.8 V to 3.6 V. At 0.8 V, it supports clock frequencies up to 20 MHz with guaranteed setup/hold times and propagation delay (tpd ≤ 17.2 ns). This makes SN74AUP1G80DCKRG4 suitable for energy-harvesting and ultra-low-voltage systems where other logic families fail to operate.

Does SN74AUP1G80DCKRG4 support partial-power-down mode, and how is it implemented?

Yes, SN74AUP1G80DCKRG4 supports partial-power-down via its Ioff feature. When VCC = 0 V, all inputs and outputs enter high-impedance state with leakage ≤0.6 µA. This prevents current backflow into powered-down sections-critical in modular systems like hot-swappable server blades where SN74AUP1G80DCKRG4 may interface between active and inactive subsystems.

Can SN74AUP1G80DCKRG4 be used as a frequency divider, and what are the design constraints?

Yes, SN74AUP1G80DCKRG4 can implement a 2:1 frequency divider by connecting Q to D. The output toggles on every rising clock edge, halving the input frequency. However, the initial state is undefined; an external override circuit (e.g., pull-up/pull-down with enable) is required for deterministic startup. SN74AUP1G80DCKRG4's 250 mV hysteresis helps suppress noise-induced false toggling in this configuration.

What is the significance of the Schmitt-trigger input in SN74AUP1G80DCKRG4?

The Schmitt-trigger input in SN74AUP1G80DCKRG4 provides 250 mV typical hysteresis at 3.3 V, enabling reliable switching even with slow-rising or noisy clock/data signals. This eliminates external RC filtering in applications like factory automation encoders or capacitive touch interfaces-where SN74AUP1G80DCKRG4 directly conditions marginal signals before latching.

Is SN74AUP1G80DCKRG4 compatible with 3.3-V I/O systems while operating at lower supply voltages?

Yes, SN74AUP1G80DCKRG4 features 3.6-V I/O tolerance, meaning its inputs and outputs safely accept and drive signals up to 3.6 V regardless of VCC setting-even when VCC = 0.8 V. This allows SN74AUP1G80DCKRG4 to serve as a voltage-level translator between 3.3-V peripherals and sub-1-V microcontrollers without external components.
