Texas Instruments SN74AUP1G80DRYR

Overview

SN74AUP1G80 from Texas Instruments is a single positive-edge-triggered D-type flip-flop in a 6-pin SON package (1.00 mm × 1.45 mm), operating across 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 Ioff support for partial-power-down mode - used for clock frequency division and data synchronization in ultra-low-power portable systems.

For engineers reviewing the SN74AUP1G80 datasheet, SN74AUP1G80 pinout, SN74AUP1G80 application, or SN74AUP1G80 equivalent, this page delivers verified functional role, confirmed timing specs (tpd, tsu, th), validated package mapping (SON-6), real-world use cases in battery-powered automation and signal integrity–sensitive point-to-point interfaces, and two technically documented alternative parts with explicit functional and application differences.

Technical Context

This device implements a synchronous edge-triggered storage element where data transfer occurs strictly on the positive-going clock transition, independent of input slew rate due to voltage-level–based triggering. Its Schmitt-trigger–enhanced inputs (250 mV typical hysteresis at 3.3 V) tolerate slow transitions and improve noise immunity.

The AUP family architecture enables ultra-low static power (0.9 µA max ICC) and dynamic power (Cpd = 4.3 pF typical at 3.3 V) while maintaining rail-to-rail output swing and 3.6-V I/O tolerance - critical for mixed-voltage domain interfacing in space-constrained embedded designs.

FAQ

What is the maximum clock frequency supported by SN74AUP1G80 at 1.8 V?

The SN74AUP1G80 supports up to 240 MHz maximum clock frequency at 1.8 V ± 0.15 V over the full –40°C to +85°C temperature range, as specified in Section 6.8 (Switching Characteristics, CL = 5 pF). This value assumes proper load capacitance control and stable 1.8-V supply regulation - exceeding it risks setup/hold violations and metastability. The SN74AUP1G80 datasheet confirms this limit under standard test conditions with 5-pF load.

Does SN74AUP1G80 require external pull-up or pull-down resistors on unused pins?

No - SN74AUP1G80 has no internal weak pull-ups or pull-downs, but its CMOS inputs must never float. Unused inputs (D or CLK) must be externally tied to VCC or GND per TI's SCBA004 guideline to prevent undefined logic states and excessive ICC. The NC pin (pin 5 in DRY package) is unconnected and may be left floating or grounded per PCB layout rules, but must not be driven.

Can SN74AUP1G80 operate reliably at 0.85 V supply voltage?

Yes - SN74AUP1G80 is fully characterized down to 0.8 V, including timing (tpd = 17.2 ns max at 0.8 V, TA = 25°C) and DC parameters (VOH ≥ VCC – 0.1 V). At 0.85 V, it meets all recommended operating conditions: tsu = 6.7 ns, th = 1 ns, and fclock = 20 MHz minimum. Operation below 0.8 V is outside specification and not guaranteed.

How does the Ioff feature function in SN74AUP1G80 during power sequencing?

When VCC drops to 0 V, the SN74AUP1G80's Ioff circuitry places both D and Q terminals into high-impedance state, limiting leakage to ≤0.6 µA (TA = 85°C). This prevents current backflow from live signal lines into the unpowered device - critical during staggered power-up/down in multi-rail systems. The feature activates automatically; no enable pin or configuration is needed. SN74AUP1G80 remains safe even if inputs are driven while VCC = 0 V.

Is SN74AUP1G80 pin-compatible with SN74AUP1G74 in the same DRY package?

No - SN74AUP1G80 (D-type flip-flop) and SN74AUP1G74 (dual-set/dual-reset flip-flop) have different pinouts in the DRY package. SN74AUP1G80 uses pins 1(D), 2(CLK), 3(GND), 4(Q), 5(NC), 6(VCC); SN74AUP1G74 uses pins 1(CLK), 2(D), 3(GND), 4(Q), 5(/Q), 6(VCC). Swapping them causes functional failure and potential I/O contention. Always verify pin mapping using TI's official package drawings for SN74AUP1G80.
