Texas Instruments SN74AUP2G34DSFR

Overview

SN74AUP2G34DSFR from Texas Instruments is a dual non-inverting buffer gate in a 6-pin X2SON (DSF) package, optimized for ultra-low-power operation across 0.8 V to 3.6 V supply range. It delivers 4.3 ns max propagation delay at 3.3 V, 1.5 pF typical input capacitance, and supports partial-power-down via Ioff, making it ideal for battery-powered portable logic interfacing.

For engineers reviewing the SN74AUP2G34DSFR datasheet, SN74AUP2G34DSFR pinout, SN74AUP2G34DSFR application, or SN74AUP2G34DSFR equivalent, key selection criteria include its sub-1 µA static ICC (0.9 mA max), 4.3 pF typical dynamic power dissipation, I/O tolerance up to 3.6 V, and guaranteed operation down to 0.8 V - critical for mixed-voltage, space-constrained, and energy-sensitive designs.

Technical Context

The SN74AUP2G34DSFR implements two independent positive-logic buffers (Y = A), with each channel featuring rail-to-rail output swing and symmetric drive strength (±4 mA at 3 V). Its AUP family architecture minimizes both static leakage (ICC ≤ 0.9 mA) and dynamic switching loss (Cpd = 4.3 pF typ at 3.3 V), enabling stable performance across the full 0.8–3.6 V VCC range.

Designed for point-to-point signal buffering, the device integrates Ioff circuitry that disables outputs during partial power-down, preventing backflow current when VCC = 0 V. Input thresholds scale with VCC (e.g., VIH = 2.0 V min at VCC = 3.0–3.6 V), and ESD robustness meets 2000-V HBM and 1000-V CDM per JESD22.

FAQ

What is the minimum operating voltage for SN74AUP2G34DSFR?

The SN74AUP2G34DSFR operates down to 0.8 V, enabling direct integration with emerging ultra-low-voltage microcontrollers and energy-harvesting subsystems. At 0.8 V, it maintains functional logic levels and specified timing margins, as validated across –40°C to 85°C ambient temperature.

Does SN74AUP2G34DSFR support partial power-down mode?

Yes, the SN74AUP2G34DSFR features integrated Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow from live I/O pins into the unpowered device - essential for hot-swap and modular system architectures.

What is the maximum propagation delay of SN74AUP2G34DSFR at 3.3 V?

The SN74AUP2G34DSFR has a maximum propagation delay (tpd) of 4.3 ns at VCC = 3.3 V with CL = 15 pF, measured from input transition (20%–80%) to output transition (20%–80%), ensuring predictable timing in high-speed digital signal paths.

Is SN74AUP2G34DSFR pin-compatible with other 6-pin logic devices in TI's portfolio?

The SN74AUP2G34DSFR uses the DSF (X2SON-6) package with standardized 0.5 mm pitch and pin 1 marking. It shares mechanical footprint compatibility with SN74LVC2G34DSFR and SN74AUC2G34DSFR, though electrical behavior and thermal characteristics differ per family specification.

What is the input capacitance of SN74AUP2G34DSFR, and why does it matter?

The SN74AUP2G34DSFR has a typical input capacitance (Ci) of 1.5 pF. This low value minimizes capacitive loading on upstream drivers, preserves signal edge rates in high-frequency or long-trace applications, and reduces dynamic power consumption in densely routed PCBs.
