Product details

Overview

SN74AUP1G34DBVR 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 SOT-23-5 packages for space-constrained portable and battery-powered systems.

For engineers reviewing the SN74AUP1G34DBVR datasheet, SN74AUP1G34DBVR pinout, SN74AUP1G34DBVR application, or SN74AUP1G34DBVR equivalent, key selection criteria include I_off support for live insertion and partial power-down, input hysteresis (250 mV typ) for noise immunity on slow transitions, 3.6-V I/O tolerance enabling mixed-voltage interfacing, and ultra-low dynamic/static power consumption critical for energy-sensitive designs.

Technical Context

This device belongs to TI's AUP (Advanced Ultra-Low-Power) logic family, optimized for sub-1-μA ICC operation while maintaining robust signal integrity across 0.8–3.6 V. Its architecture integrates input hysteresis and controlled edge rates to suppress overshoot/undershoot (<10% of V_CC) without external termination.

The SN74AUP1G34DBVR implements a non-inverting buffer with fully specified I_off functionality, allowing safe voltage presence on inputs/outputs during V_CC = 0 V conditions. It supports down-translation (e.g., 3.3-V peripheral to 1.0-V microcontroller) and meets JESD 78 Class II latch-up (>100 mA) and JESD 22 ESD (2000-V HBM, 1000-V CDM) requirements.

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 core logic, 1.2-V I/O, and 3.3-V peripherals 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 control paths.
I_CC Max	0.9 μA at 25°C - extends battery life in always-on sensor nodes and wearable devices.
C_pd	4.1 pF typ at 3.3 V - minimizes dynamic power draw in high-frequency toggle applications (e.g., clock distribution).
I_off	0.6 μA max at V_CC = 0 V - prevents back-drive current during hot-swap or partial power-down sequences.
V_IH/V_IL	V_IH = 2.0 V, V_IL = 0.9 V at V_CC = 3.3 V - provides clear logic thresholds compatible with standard 3.3-V CMOS drivers.
Input Hysteresis	250 mV typ at 3.3 V - rejects noise on slow-rising/falling signals (e.g., mechanical switch debouncing, analog sensor outputs).

Pinout & Package

SOT-23-5 (DBV) package: 1.60 mm × 1.20 mm body, 0.95 mm height, 0.95 mm pitch, lead-free NiPdAu/Sn finish, MSL Level-1.

Pin/Terminal	Circuit Role	Design Meaning
1 (NC)	No internal connection	Unused pin; must be left unconnected or tied to GND/V_CC per layout guidelines - no electrical function.
2 (A)	Input	CMOS-compatible input accepting 0–3.6 V; includes hysteresis for noise immunity and supports slow edges.
3 (GND)	Ground reference	Primary return path for logic and power currents; requires low-inductance connection to system ground plane.
4 (Y)	Output	Push-pull CMOS output driving up to ±4 mA at 3.0 V; 3.6-V tolerant when V_CC ≤ 3.6 V.
5 (V_CC)	Power supply	Single-supply rail supporting 0.8–3.6 V; requires local 0.1-μF ceramic bypass capacitor placed adjacent to pin.

Key Features

Feature	Design Value
Ultra-low static power	0.9 μA max I_CC enables multi-year battery operation in IoT endpoint sensors and wearables.
I_off protection	Blocks current flow when V_CC = 0 V - essential for hot-pluggable modules and power-gated subsystems.
3.6-V I/O tolerance	Accepts 3.3-V inputs while powered from 0.8–1.2 V - eliminates external level translators in mixed-voltage SoC interfaces.
Input hysteresis	250 mV typ threshold margin improves reliability against EMI and crosstalk in noisy industrial environments.
Low-noise switching	Overshoot/undershoot limited to <10% of V_CC - reduces EMI emissions and avoids false triggering in adjacent circuits.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G34DBVR	Wider V_CC range (1.65–5.5 V); higher I_CC (10 μA typ); no I_off; faster t_pd (3.5 ns @ 3.3 V)	Better suited for 5-V legacy systems; unsuitable for sub-1-V operation or hot-swap scenarios requiring I_off.	Select when interfacing with 5-V logic or when lower propagation delay outweighs ultra-low-power needs.
74AHC1G34SE-7	Same V_CC (2–5.5 V); higher drive strength (±8 mA); no I_off; higher C_pd (10 pF); SOT-353 package	Targeted at higher-speed, higher-drive applications; lacks I_off and sub-1-V compatibility.	Choose for cost-sensitive consumer electronics where 3.3-V-only operation and moderate power are acceptable.

Compared with SN74LVC1G34DBVR and 74AHC1G34SE-7, the SN74AUP1G34DBVR uniquely delivers sub-1-μA quiescent current, 0.8-V minimum operation, and I_off-enabled live insertion - making it the only viable option for energy-harvesting sensors and dynamically powered modular systems.

FAQ

What is the minimum supply voltage supported by the SN74AUP1G34DBVR?

The SN74AUP1G34DBVR operates down to 0.8 V, enabling direct integration with ultra-low-voltage microcontrollers and energy-harvesting power supplies. This specification is guaranteed across the full –40°C to +85°C temperature range and is validated per TI's SCES603K datasheet Section 7.3.

Does the SN74AUP1G34DBVR support live insertion or hot-swap applications?

Yes, the SN74AUP1G34DBVR includes I_off circuitry that disables outputs and blocks current backflow when V_CC = 0 V. This feature is explicitly documented in Section 9.1 and Table 1 of the SCES603K datasheet, making SN74AUP1G34DBVR suitable for modular systems requiring live insertion.

Can the SN74AUP1G34DBVR interface between a 1.0-V microcontroller and a 3.3-V peripheral?

Yes - the SN74AUP1G34DBVR accepts inputs up to 3.6 V regardless of V_CC, and its output swings rail-to-rail within the V_CC range. When powered at 1.0 V, it safely translates 3.3-V input signals to 1.0-V logic levels, as confirmed in Section 9.3 and Figure 5 of the SCES603K datasheet.

What is the purpose of the NC pin (Pin 1) on the SN74AUP1G34DBVR?

Pin 1 is a no-connect terminal with no internal bond wire or silicon connection. Per TI's DBV package drawing and Section 6 of SCES603K, it may be left floating, tied to GND, or tied to V_CC - none affects device operation. Layout best practice recommends leaving it unconnected unless required for mechanical stability.

How does input hysteresis improve noise immunity in the SN74AUP1G34DBVR?

The SN74AUP1G34DBVR features 250 mV typical input hysteresis at 3.3 V (Section 1, Features), creating distinct VIH and VIL thresholds. This prevents oscillation on slow or noisy input edges - critical for interfacing with mechanical switches, thermistor-based sensors, or long-trace industrial signals where ringing or EMI could cause false toggling.
