Product details
Overview
SN74AUP1G34DCKT from Texas Instruments is a single low-power CMOS buffer gate performing Y = A logic in positive-logic systems, operating across 0.8 V–3.6 V supply range with 4.1 ns max propagation delay at 3.3 V, 0.9 µA max ICC quiescent current, and 4.1 pF typical dynamic power capacitance - deployed in ultra-compact SC70-5 packaging for space-constrained portable electronics.
For engineers reviewing the SN74AUP1G34DCKT datasheet, SN74AUP1G34DCKT pinout, SN74AUP1G34DCKT application, or SN74AUP1G34DCKT equivalent, key selection criteria include Ioff-enabled live insertion support, 1.5 pF typical input capacitance for high-speed signal integrity, hysteresis-enhanced noise immunity (250 mV typ), and 3.6-V I/O tolerance enabling mixed-voltage level translation between 0.8 V microcontrollers and 3.3 V peripherals.
Technical Context
This device belongs to TI's Advanced Ultra-Low-Power (AUP) logic family, engineered specifically for battery-powered applications requiring sub-1 µA static power consumption while maintaining robust switching performance down to 0.8 V supply. Its architecture integrates input hysteresis (250 mV typ at 3.3 V) and controlled edge rates to suppress overshoot/undershoot (<10% of VCC).
The SN74AUP1G34DCKT implements a non-inverting buffer function with full Ioff support - disabling outputs and blocking back-drive current when VCC = 0 V - making it suitable for partial-power-down systems and hot-plug interfaces. It is not a bus transceiver or level shifter with direction control; its sole function is unidirectional signal buffering with voltage translation capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with 0.8 V–1.2 V microprocessors and 3.3 V peripherals without external level shifters. |
| tpd Max | 4.1 ns at 3.3 V, CL = 5 pF - ensures timing-critical signal routing in high-speed digital subsystems with minimal latency. |
| ICC Max | 0.9 µA at TA = –40°C to 85°C - delivers ultra-low static power for multi-year battery life in always-on sensor nodes. |
| Cpd Typ | 4.1 pF at 3.3 V - defines dynamic power dissipation (P = Cpd × V² × f); critical for estimating total system power at 10 MHz operation. |
| Ioff Max | 0.6 µA at VCC = 0 V - guarantees safe isolation during live insertion or partial power-down, preventing damaging back-current flow. |
| Input Hysteresis | 250 mV typ at 3.3 V - improves noise margin against slow-rising or noisy inputs, eliminating false triggering in industrial environments. |
| ESD Rating | 2000 V HBM, 1000 V CDM - meets JEDEC standards for robust handling in automated assembly and field-replaceable modules. |
Pinout & Package
SN74AUP1G34DCKT uses the SC70-5 (DCK) package: 1.25 mm × 1.65 mm body, 0.65 mm height, 0.65 mm pitch, 5-terminal surface-mount configuration optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused terminal; must be left floating or tied to GND/VCC per layout guidelines - no electrical function or signal path. |
| 2 (A) | Input | CMOS-compatible digital input accepting 0 V–3.6 V; supports slow transitions due to built-in hysteresis. |
| 3 (GND) | Ground reference | Primary return path for all internal logic and output current; requires low-inductance connection to system ground plane. |
| 4 (Y) | Output | Push-pull CMOS output driving up to ±4 mA at 3 V; 3.6-V tolerant - may interface directly with higher-voltage logic families. |
| 5 (VCC) | Power supply | Single-supply rail supporting 0.8 V–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 ICC enables >10-year battery operation in IoT endpoint sensors and wearable health monitors. |
| Ioff partial-power-down | Blocks back-current when VCC = 0 V - essential for modular systems where boards are inserted/removed under power. |
| 3.6-V I/O tolerance | Allows direct connection to 3.3 V buses while powered from 0.8 V–1.2 V rails - eliminates discrete level translators in MCU peripheral interfaces. |
| Input hysteresis | 250 mV typical threshold separation prevents chatter on slow or noisy signals - critical in ECG front-ends and HVAC sensor conditioning. |
| Low-noise output edges | Overshoot/undershoot limited to <10% of VCC - reduces EMI in EMC-sensitive medical and audio equipment designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DCKT | Higher ICC (10 µA typ), wider VCC (1.65–5.5 V), no Ioff, no hysteresis | Suitable for general-purpose 3.3 V/5 V systems but lacks live-insertion support and noise immunity for battery-powered edge nodes | Choose when interfacing legacy 5 V peripherals and power efficiency is secondary to voltage flexibility. |
| 74AHC1G34SE-7 | Higher drive strength (±8 mA), 2.0–5.5 V VCC, no Ioff, no hysteresis, 3.5 ns tpd at 5 V | Better for high-speed 5 V bus buffering but incompatible with sub-1 V logic and unsafe for hot-swap scenarios | Prefer for industrial PLC I/O modules requiring stronger drive and 5 V compatibility, not for ultra-low-power wearables. |
Compared with SN74LVC1G34DCKT and 74AHC1G34SE-7, the SN74AUP1G34DCKT uniquely combines sub-1 µA quiescent current, Ioff-enabled live insertion, and input hysteresis - making it the only viable choice for energy-harvested sensors and medical wearables demanding both longevity and reliability under dynamic power conditions.

FAQ
What is the maximum propagation delay of the SN74AUP1G34DCKT at 3.3 V supply?
The SN74AUP1G34DCKT has a maximum propagation delay (tpd) of 4.1 ns at VCC = 3.3 V with CL = 5 pF load, as specified in Section 7.6 of the SCES603K datasheet. This value is measured under recommended operating conditions and represents worst-case timing for design margining in high-speed digital interfaces.
Does the SN74AUP1G34DCKT support live insertion or hot-swap applications?
Yes, the SN74AUP1G34DCKT supports live insertion via its Ioff feature, which disables outputs and blocks back-current flow when VCC = 0 V. This allows safe board replacement in powered-backplane systems like ATCA chassis without disrupting upstream power domains or damaging connected components.
Can the SN74AUP1G34DCKT interface between a 0.8 V microcontroller and a 3.3 V peripheral?
Yes, the SN74AUP1G34DCKT can perform this voltage translation: it operates from 0.8 V to 3.6 V and features 3.6-V tolerant I/O. When powered at 0.8 V, its inputs accept up to 3.6 V, and its output swings rail-to-rail within the 0.8 V supply - enabling direct connection to 3.3 V receivers with appropriate level thresholds.
What is the input hysteresis voltage of the SN74AUP1G34DCKT and why does it matter?
The SN74AUP1G34DCKT provides 250 mV typical input hysteresis at 3.3 V supply, meaning the difference between VIH and VIL thresholds is ~250 mV. This prevents oscillation on slow-rising or electrically noisy inputs - a critical advantage in biomedical sensor interfaces and industrial control lines where signal integrity cannot be compromised.
Is a bypass capacitor required for stable operation of the SN74AUP1G34DCKT?
Yes, a 0.1 µF ceramic bypass capacitor is required between VCC (Pin 5) and GND (Pin 3) and must be placed as close as possible to the device. This stabilizes the supply during output switching events, minimizes ground bounce, and ensures reliable operation across the full –40°C to 85°C temperature range per TI's layout recommendations.
