Product details
Overview
SN74AUP1G34DBVT from Texas Instruments is a single low-power CMOS buffer gate (Y = A) in SOT-23-5 package, operating from 0.8 V to 3.6 V supply, 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 - used for level translation and signal conditioning in ultra-low-power portable electronics.
For engineers reviewing the SN74AUP1G34DBVT datasheet, SN74AUP1G34DBVT pinout, SN74AUP1G34DBVT application, or SN74AUP1G34DBVT equivalent, key selection criteria include Ioff support for live insertion, input hysteresis (250 mV typ) for noise immunity, 3.6-V I/O tolerance enabling mixed-voltage interfacing, and ultra-small footprint compatibility with space-constrained PCB layouts.
Technical Context
This device belongs to TI's AUP (Advanced Ultra-Low-Power) logic family, designed specifically for battery-powered systems requiring sub-1-μA static current and robust operation across wide voltage ranges. Its buffered output drives capacitive loads up to 30 pF while maintaining controlled edge rates to limit overshoot/undershoot.
The internal circuit implements positive-logic non-inverting buffering with input hysteresis and Ioff protection. When VCC = 0 V, inputs and outputs are high-impedance and tolerate up to 3.6 V - enabling safe partial-power-down and hot-plug operation without back-drive current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - supports direct interface with 0.8–1.2 V microcontrollers and 3.3 V peripherals without external level shifters. |
| tpd (max) | 4.1 ns at 3.3 V, CL = 5 pF - enables timing-critical signal routing in high-speed low-power subsystems. |
| ICC (max) | 0.9 μA at 3.6 V - ensures multi-year battery life in always-on sensor nodes and wearable devices. |
| Cpd | 4.1 pF typ at 3.3 V - defines dynamic power consumption (P = Cpd × V2 × f), critical for optimizing switching efficiency. |
| Vhys | 250 mV typ at 3.3 V - suppresses false triggering from slow-rising or noisy inputs (e.g., mechanical switches, analog sensor outputs). |
| Ioff | 0.6 μA max at VCC = 0 V - prevents damaging back-current flow during power sequencing or board hot-swap events. |
| Input Capacitance | 1.5 pF typ - minimizes loading on high-impedance source signals such as crystal oscillator outputs or ADC reference buffers. |
Pinout & Package
SOT-23-5 (DBV) package: 1.60 mm × 1.20 mm body size, 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 pad - must be left floating or grounded per layout guidelines; no electrical function. |
| 2 (A) | Input | CMOS-compatible digital input with hysteresis; accepts 0–3.6 V regardless of VCC value. |
| 3 (GND) | Ground reference | Primary return path for all internal logic and output current; requires low-inductance PCB connection. |
| 4 (Y) | Output | Push-pull CMOS output capable of sourcing/sinking ±4 mA at 3 V; 3.6-V tolerant when VCC ≤ 3.6 V. |
| 5 (VCC) | Power supply | Single-supply rail for core logic and output drivers; bypass capacitor (0.1 μF) required adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | 0.9 μA max ICC enables >10-year coin-cell operation in IoT endpoint sensors. |
| Ioff protection | Blocks current flow between powered/unpowered domains - essential for modular system architectures with hot-swap capability. |
| Input hysteresis | 250 mV threshold margin rejects EMI-induced glitches on long traces or unshielded cables. |
| 3.6-V I/O tolerance | Allows direct connection to 3.3-V buses while operating from 1.0-V or 1.2-V rails - eliminates discrete level translators. |
| Wide VCC range | 0.8–3.6 V operation supports legacy 3.3-V designs and next-gen sub-1-V processors without redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DBVT | Higher ICC (10 μA typ), narrower VCC range (1.65–5.5 V), no Ioff or hysteresis | Requires stable ≥1.65 V supply; unsuitable for partial-power-down or noisy sensor interfaces | Select when higher drive strength (±24 mA) and 5-V compatibility outweigh ultra-low-power needs. |
| 74AHC1G34SE-7 | Wider VCC (2–5.5 V), higher Cpd (10 pF), no Ioff, no hysteresis | Not usable below 2 V; lacks live-insertion support and noise immunity for battery-operated designs | Prefer for industrial control boards with fixed 3.3/5-V rails where cost is primary constraint. |

FAQ
What is the maximum operating temperature range for SN74AUP1G34DBVT?
The SN74AUP1G34DBVT is rated for operation from –40°C to +85°C ambient temperature, validated per JEDEC JESD78 latch-up testing (>100 mA) and JESD22 ESD standards (2000-V HBM). This range supports deployment in consumer wearables, portable medical devices, and industrial handheld tools without thermal derating.
Does SN74AUP1G34DBVT support level translation between different supply voltages?
Yes, SN74AUP1G34DBVT supports bidirectional level translation: its inputs tolerate up to 3.6 V regardless of VCC (as low as 0.8 V), and its outputs swing rail-to-rail within the VCC range. This enables reliable interfacing between 3.3-V peripherals and sub-1-V microcontrollers without external components.
How does the Ioff feature of SN74AUP1G34DBVT protect system-level circuits?
The Ioff circuitry in SN74AUP1G34DBVT disables output drivers and isolates input/output terminals when VCC = 0 V, limiting leakage current to ≤0.6 μA. This prevents back-driving powered sections of the PCB during hot-swap events or partial power-down - protecting upstream voltage regulators and downstream logic from damage or data corruption.
Can SN74AUP1G34DBVT drive a 30-pF capacitive load at 3.3 V while meeting timing specs?
Yes, SN74AUP1G34DBVT guarantees tpd ≤ 6.5 ns at 3.3 V with CL = 30 pF (per Section 7.9 of SCES603K), and maintains <10% overshoot/undershoot. Its 4.1 pF Cpd and controlled edge rates ensure predictable timing and signal integrity even under worst-case capacitive loading conditions.
Is SN74AUP1G34DBVT pin-compatible with other SOT-23-5 logic gates?
SN74AUP1G34DBVT uses standard SOT-23-5 pinout (NC, A, GND, Y, VCC) per TI's DBV mechanical drawing. It is pin-compatible with SN74AUP1G04DBVT (inverter), SN74AUP1G07DBVT (open-drain buffer), and SN74AUP1G08DBVT (AND gate) - enabling drop-in functional substitution in existing layouts with identical footprint and solder reflow profile.
