Texas Instruments SN74AUP1G80DCKRE4

Overview

SN74AUP1G80 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, 0.9 µA max ICC, and 1.5 pF typical input capacitance. It enables low-power clock synchronization and data latching in battery-powered portable systems.

For engineers reviewing the SN74AUP1G80 datasheet, SN74AUP1G80 pinout, SN74AUP1G80 application, or SN74AUP1G80 equivalent, key selection criteria include its ultra-low static/dynamic power consumption, Ioff partial-power-down support, Schmitt-trigger input hysteresis (250 mV typ), 3.6-V I/O tolerance, and verified performance across –40°C to +85°C.

Technical Context

The SN74AUP1G80 implements a synchronous edge-triggered storage element with voltage-level clock detection-unaffected by input rise time-and supports true single-cycle data capture when setup/hold timing is met. Its balanced CMOS push-pull output drives light loads with minimal overshoot/undershoot (<10% of VCC).

Designed for mixed-voltage signal domains, it features over-voltage tolerant inputs (up to 4.6 V), Ioff circuitry that disables outputs during power-down to prevent backflow, and Schmitt-trigger action on inputs for robust noise immunity against slow transitions.

FAQ

What is the minimum supply voltage required for reliable operation of SN74AUP1G80DCKRE4?

The SN74AUP1G80DCKRE4 operates reliably from 0.8 V to 3.6 V. At 0.8 V, it maintains functional timing with fclock ≥20 MHz and tpd ≤17.2 ns (CL = 5 pF, TA = 25°C). Below 0.8 V, device behavior is not characterized and may result in metastability or failure to meet setup/hold requirements. Always verify voltage rail stability under load in final designs using SN74AUP1G80DCKRE4.

Does SN74AUP1G80DCKRE4 support partial power-down mode, and how is it implemented?

Yes, SN74AUP1G80DCKRE4 supports partial power-down via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables all outputs, limiting leakage to ≤0.6 µA per pin. This prevents current backflow into powered sections of the system-a critical requirement in multi-rail hot-swap architectures. The feature is intrinsic to the silicon design and requires no external control signals to activate SN74AUP1G80DCKRE4.

Can SN74AUP1G80DCKRE4 be used as a frequency divider, and what are the layout considerations?

Yes, SN74AUP1G80DCKRE4 can implement a 2× frequency divider by connecting Q to D. TI confirms this configuration in the datasheet's Typical Application section. Layout requires a series resistor (e.g., 10 kΩ) on the Q→D feedback path to resolve initial state ambiguity and prevent contention during override initialization. Avoid stubs longer than 5 mm on CLK/D/Q traces to preserve 4.4 ns tpd performance in SN74AUP1G80DCKRE4.

What is the significance of the Schmitt-trigger input in SN74AUP1G80DCKRE4, and how does it affect system design?

The Schmitt-trigger input in SN74AUP1G80DCKRE4 provides 250 mV typical hysteresis at 3.3 V, enabling robust operation with slow-rising clock or control signals (e.g., from RC networks or mechanical switches). This eliminates external conditioning circuits and reduces susceptibility to noise-induced false triggering. Designers can directly connect SN74AUP1G80DCKRE4 to debounced buttons or filtered sensor outputs without additional components.

Is SN74AUP1G80DCKRE4 compatible with 5-V logic systems, and what are the voltage limitations?

SN74AUP1G80DCKRE4 supports 3.6-V I/O tolerance-inputs may safely accept voltages up to 4.6 V (per Absolute Maximum Ratings), but VCC must remain ≤3.6 V. It is not 5-V tolerant. For 5-V system interfacing, use level translators or select alternatives like SN74LVC1G80DBVR. Direct connection of SN74AUP1G80DCKRE4 to 5-V buses risks permanent damage and violates JEDEC stress limits.
