Texas Instruments SN74AUP1G34DPWR

Overview

SN74AUP1G34DPWR from Texas Instruments is a single low-power CMOS buffer gate performing Y = A in positive logic, operating across 0.8 V to 3.6 V supply range, with 4.1 ns max propagation delay at 3.3 V, 4.1 pF typical dynamic power capacitance, and 0.9 μA max quiescent current - deployed in ultra-compact X2SON-5 (0.8 mm × 0.8 mm) for space-constrained portable and battery-powered signal conditioning.

For engineers reviewing the SN74AUP1G34DPWR datasheet, SN74AUP1G34DPWR pinout, SN74AUP1G34DPWR application, or SN74AUP1G34DPWR equivalent, key selection criteria include I_off-enabled live insertion support, 3.6-V I/O tolerance for mixed-voltage level translation, input hysteresis (250 mV typ at 3.3 V) for noise immunity, and ultra-low static/dynamic power consumption in sub-1-mm² packaging.

Technical Context

This device belongs to TI's AUP (Advanced Ultra-Low-Power) logic family, optimized for battery-operated systems requiring stable signal buffering across wide V_CC ranges. Its architecture integrates I_off circuitry enabling partial power-down operation and back-drive protection when V_CC = 0 V, while built-in input hysteresis improves robustness against slow or noisy transitions.

The SN74AUP1G34DPWR uses standard CMOS output drive with balanced rise/fall characteristics, delivering ±4 mA output current at 3 V, and supports load capacitances up to 30 pF. It exhibits no internal enable control - function is always active - and requires all unused inputs to be tied to V_CC or GND per design guidelines.

FAQ

What is the maximum operating temperature range for the SN74AUP1G34DPWR?

The SN74AUP1G34DPWR is rated for operation from –40°C to +85°C ambient temperature, meeting industrial-grade thermal requirements. This range is validated across all electrical specifications including propagation delay, output drive, and I_off performance, and applies to the X2SON-5 package under standard JEDEC mounting conditions.

Does the SN74AUP1G34DPWR support level translation between different supply voltages?

Yes, the SN74AUP1G34DPWR supports bidirectional level translation: its inputs tolerate up to 3.6 V regardless of V_CC, and its outputs swing rail-to-rail between GND and V_CC. For example, with V_CC = 1.2 V, it accepts 3.3-V inputs and outputs 1.2-V logic - enabling seamless interfacing between 3.3-V peripherals and sub-1.2-V processors without external components.

Is a bypass capacitor required for stable operation of the SN74AUP1G34DPWR?

Yes, a 0.1-μF ceramic bypass capacitor is required between V_CC and GND, placed within 2 mm of the SN74AUP1G34DPWR pins. This mitigates supply noise and prevents voltage droop during output transitions, especially critical given the device's ultra-low I_CC and sensitivity to transient coupling in high-density layouts.

Can the NC pin (Pin 1) of the SN74AUP1G34DPWR be left floating or grounded?

Pin 1 is a true no-connect (NC) with no internal bond wire or silicon connection. It must remain unconnected - neither grounded nor tied to V_CC. Routing traces to or placing solder mask openings on Pin 1 may introduce parasitic capacitance or contamination risk; best practice is to omit any pad connection entirely in layout.

How does the input hysteresis of the SN74AUP1G34DPWR improve system reliability?

The SN74AUP1G34DPWR features 250 mV typical input hysteresis at 3.3 V, creating distinct VIH and VIL thresholds that prevent oscillation during slow or noisy signal transitions. This eliminates need for external Schmitt triggers in applications like thermistor-based HVAC sensors or ECG electrode interfaces where signal slew rates fall below 200 ns/V.
