Product details

Overview

SN74AUP1G34YZPR 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 DSBGA-5 (0.79 mm × 0.79 mm) for space-constrained portable electronics.

For engineers reviewing the SN74AUP1G34YZPR datasheet, SN74AUP1G34YZPR pinout, SN74AUP1G34YZPR application, or SN74AUP1G34YZPR equivalent, key selection criteria include I_off-enabled live insertion support, 3.6-V I/O tolerance for mixed-voltage translation, input hysteresis (250 mV typ at 3.3 V) for noise immunity, and ultra-low 1.5 pF input capacitance enabling high-speed signal integrity in battery-powered systems.

Technical Context

This device belongs to TI's AUP (Advanced Ultra-Low-Power) logic family, engineered for sub-1-μA static power consumption and optimized for voltage translation between 0.8 V–1.2 V microcontrollers and 3.3 V peripherals. Its architecture integrates I_off circuitry that disables outputs when V_CC = 0 V, preventing back-drive current and supporting partial power-down modes.

The SN74AUP1G34YZPR implements a non-inverting buffer with balanced output drive, slow edge rates to suppress overshoot/undershoot (<10% of V_CC), and input hysteresis to tolerate slow-rising signals and improve noise margin - all while maintaining full functionality across –40°C to +85°C industrial temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	0.8 V to 3.6 V - enables direct interface with 0.8 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters.
t_pd Max	4.1 ns at 3.3 V, CL = 5 pF - ensures timing-critical signal buffering in high-speed digital interfaces up to ~240 MHz.
I_CC Max	0.9 μA at 3.6 V - delivers ultra-low static power for multi-year battery life in always-on sensor nodes and wearables.
C_pd	4.1 pF typ at 3.3 V - minimizes dynamic switching power, critical for high-frequency operation in energy-sensitive applications.
C_i	1.5 pF typ - reduces capacitive loading on driving sources, preserving signal rise/fall times in high-impedance or long-trace paths.
V_IO Tolerance	3.6 V I/O tolerant - allows inputs to accept 3.3 V signals even when V_CC = 0.8 V, enabling robust down-translation from legacy peripherals.
I_off	0.6 μA max at V_CC = 0 V - guarantees safe live insertion and back-drive protection during hot-swap or partial power-down sequences.

Pinout & Package

SN74AUP1G34YZPR uses a 5-pin DSBGA (YZP) package measuring 0.79 mm × 0.79 mm with 0.4-mm pitch, featuring bottom-side solder balls and no internal connection on Pin 1 (N.C.). The package supports automated placement and reflow in high-density PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1 (N.C.)	No internal connection	Unused pad; must be left floating or grounded per layout guidelines - no electrical function or signal path.
2 (A)	Input	CMOS-compatible digital input accepting 0 V to 3.6 V; includes hysteresis (250 mV typ) for noise immunity on slow edges.
3 (GND)	Ground reference	Primary return path for logic and power; requires low-inductance connection to system ground plane.
4 (Y)	Output	Push-pull CMOS output capable of ±4 mA drive at 3 V; exhibits low overshoot/undershoot due to controlled edge rates.
5 (V_CC)	Power supply	Single-supply rail (0.8–3.6 V); requires local 0.1-μF ceramic bypass capacitor placed adjacent to this pin.

Key Features

Feature	Design Value
Ultra-low static power	0.9 μA max I_CC enables >10-year battery life in coin-cell-powered IoT endpoints and medical sensors.
I_off protection	Prevents destructive back-current flow when V_CC = 0 V - essential for hot-pluggable modules and modular system architectures.
Input hysteresis	250 mV typical threshold separation improves noise rejection on noisy PCBs or long flex-cable interconnects.
3.6-V I/O tolerance	Supports reliable interfacing to 3.3 V peripherals while powered from 0.8–1.2 V rails - eliminates external level translators.
Low-noise output edges	Overshoot/undershoot limited to <10% of V_CC, reducing EMI and eliminating need for series termination resistors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar buffer gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice

FAQ

What is the maximum operating temperature range for SN74AUP1G34YZPR?

The SN74AUP1G34YZPR is fully specified for industrial operation from –40°C to +85°C. All electrical characteristics - including propagation delay, output drive, and I_off leakage - are guaranteed across this full range, making SN74AUP1G34YZPR suitable for deployment in harsh environments such as HVAC controllers and field transmitters.

Does SN74AUP1G34YZPR support live insertion or hot-swap applications?

Yes, SN74AUP1G34YZPR supports live insertion via its integrated I_off circuitry, which disables outputs and limits leakage to 0.6 μA max when V_CC = 0 V. This prevents damaging back-current flow during hot-plug events - a key requirement for modular medical devices and field-replaceable embedded computing modules using SN74AUP1G34YZPR.

Can SN74AUP1G34YZPR translate 3.3-V signals to a 0.9-V microcontroller?

Yes, SN74AUP1G34YZPR accepts 3.3-V input signals while powered from as low as 0.8 V, thanks to its 3.6-V I/O tolerance and input hysteresis. When V_CC = 0.9 V, SN74AUP1G34YZPR outputs a valid 0.9-V logic-high signal - enabling direct down-translation without external level shifters in ultra-low-voltage MCU systems.

What is the recommended bypass capacitor for SN74AUP1G34YZPR?

A 0.1-μF X7R ceramic capacitor placed within 2 mm of the V_CC pin (Pin 5) is recommended for SN74AUP1G34YZPR. This value provides optimal high-frequency decoupling for the device's ultra-low-power operation and fast switching behavior, minimizing supply noise-induced jitter or false triggering in sensitive signal paths.

Is SN74AUP1G34YZPR pin-compatible with other AUP-family single-gate buffers?

SN74AUP1G34YZPR shares identical pinout (YZP package) and functional behavior with SN74AUP1G04YZPR, SN74AUP1G08YZPR, and SN74AUP1G14YZPR - all use Pin 1 (N.C.), Pin 2 (input), Pin 3 (GND), Pin 4 (output), Pin 5 (V_CC). This allows drop-in replacement across inverting, AND, and Schmitt-trigger variants in space-constrained layouts using SN74AUP1G34YZPR footprint.
