Product details
Overview
SN74AUP1G34YFPR 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-4 (0.79 mm × 0.79 mm) for space-constrained portable sensor interfaces and voltage-level translation.
For engineers reviewing the SN74AUP1G34YFPR datasheet, SN74AUP1G34YFPR pinout, SN74AUP1G34YFPR application, or SN74AUP1G34YFPR equivalent, key selection criteria include its Ioff-enabled live insertion capability, input hysteresis (250 mV typ at 3.3 V) for noise immunity on slow transitions, 3.6-V I/O tolerance supporting mixed-voltage signal translation, and ultra-low 1.5 pF typical input capacitance minimizing loading on high-impedance sources.
Technical Context
This device belongs to TI's AUP (Advanced Ultra-Low-Power) logic family, optimized for battery-powered systems requiring sub-1-μA static current and robust operation down to 0.8 V. Its architecture integrates Ioff circuitry that disables outputs when VCC = 0 V, preventing back-drive current and enabling hot-plug functionality.
The SN74AUP1G34YFPR implements a non-inverting buffer with hysteresis on the input stage to suppress switching noise, and features edge-rate control to limit overshoot/undershoot (<10% of VCC). It supports down-translation from 3.3-V peripherals to sub-1.2-V microcontrollers without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with 0.8-V cores, 1.2-V I/Os, and 3.3-V legacy peripherals |
| tpd Max | 4.1 ns at 3.3 V, CL = 5 pF - ensures timing-critical signal buffering in high-speed sensor readout paths |
| ICC Max | 0.9 μA at TA = –40°C to 85°C - sustains multi-year battery life in always-on wearable monitors |
| Cpd Typ | 4.1 pF at 3.3 V - defines dynamic power consumption (P = Cpd × V² × f), critical for thermal management in dense layouts |
| Ci Typ | 1.5 pF - minimizes capacitive loading on high-impedance analog sensor outputs or crystal oscillator nodes |
| Ioff Max | 0.6 μA at VCC = 0 V - guarantees safe partial-power-down operation during system sleep modes |
| Vhys Typ | 250 mV at 3.3 V - provides noise margin against EMI-induced glitches on long PCB traces or flex cables |
Pinout & Package
SN74AUP1G34YFPR uses a 4-ball DSBGA (YFP) package measuring 0.79 mm × 0.79 mm with 0.4-mm pitch, designed for ultra-dense portable PCBs. Ball assignment follows standard DSBGA top-view orientation with corner ball A1 as VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Input A | CMOS-compatible digital input with hysteresis; accepts 0–3.6 V regardless of VCC |
| B1 | GND | Dedicated ground reference for internal logic and output driver return path |
| A2 | VCC | Single power supply pin; must be bypassed with 0.1-μF capacitor placed ≤1 mm from ball |
| B2 | Output Y | Push-pull CMOS output capable of ±4 mA drive at 3 V; supports 3.6-V tolerant signaling |
Key Features
| Feature | Design Value |
|---|---|
| Ioff support | Enables live insertion and partial power-down by disabling outputs when VCC = 0 V, preventing back-current flow |
| Input hysteresis | 250 mV typical at 3.3 V - rejects noise spikes and stabilizes switching on slow-rising signals from RC networks or sensors |
| 3.6-V I/O tolerance | Allows input/output voltages up to 3.6 V independent of VCC - simplifies level translation between 3.3-V peripherals and 1.0-V processors |
| Ultra-low Ci | 1.5 pF typical input capacitance - reduces signal distortion and timing skew when driving long traces or high-Z nodes |
| Low-noise edges | Controlled slew rate limits overshoot/undershoot to <10% of VCC - eliminates need for external termination in most point-to-point links |
Applications
| Medical Sensor Interface | Wearable Biometric Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34YZPR | Higher ICC (10 μA typ), wider VCC (1.65–5.5 V), no Ioff, no hysteresis | Suitable for higher-voltage industrial control but lacks live-insertion and noise immunity for portable medical use | Choose only if system operates ≥1.65 V and does not require partial power-down or noise-hardened inputs |
| NC7SZ34P5X | Smaller 5-pin SOT-353 package, 3.6-V tolerant, but ICC = 2 μA typ and no Ioff support | Acceptable for cost-sensitive consumer electronics where board space is constrained but hot-swap is unnecessary | Select when footprint is primary constraint and system never powers down partially or requires back-drive protection |
Compared with SN74LVC1G34YZPR and NC7SZ34P5X, SN74AUP1G34YFPR uniquely delivers sub-1-μA quiescent current, Ioff-enabled live insertion, and input hysteresis - making it the only choice for battery-powered medical wearables requiring guaranteed signal integrity and zero-leakage sleep states.

FAQ
What is the maximum operating temperature range for SN74AUP1G34YFPR?
The SN74AUP1G34YFPR is rated for operation from –40°C to +85°C ambient temperature, as confirmed in Section 7.3 (Recommended Operating Conditions) of the SCES603K datasheet. This range supports deployment in clinical environments, wearable devices exposed to body heat, and industrial field transmitters operating near HVAC equipment.
Does SN74AUP1G34YFPR support live insertion or hot-swap applications?
Yes, SN74AUP1G34YFPR supports live insertion via its Ioff feature, which disables outputs when VCC = 0 V and limits off-state current to 0.6 μA max. This prevents damaging back-current flow during board replacement or modular subsystem upgrades - a requirement explicitly validated in Section 9.3 and Table 7.5 of the official datasheet.
What is the input hysteresis voltage of SN74AUP1G34YFPR and why does it matter?
The SN74AUP1G34YFPR has 250 mV typical input hysteresis at 3.3 V supply, as specified in Section 1 (Features) and Section 9.3. This hysteresis improves noise immunity on slow-transitioning signals - such as those from RC-filtered sensor outputs or long flex-cable runs - by preventing multiple toggles due to EMI or ringing near the logic threshold.
Can SN74AUP1G34YFPR translate 3.3-V signals to a 1.0-V microcontroller I/O?
Yes, SN74AUP1G34YFPR can translate 3.3-V inputs to a 1.0-V system because its inputs are 3.6-V tolerant and its VCC can operate as low as 0.8 V. When powered at 1.0 V, it correctly interprets 3.3-V logic-high inputs and outputs compatible 1.0-V logic levels - a capability documented in Section 9.1 and Section 10.1 of the datasheet.
What is the package type and ball count of SN74AUP1G34YFPR?
SN74AUP1G34YFPR uses a 4-ball DSBGA (Die Size Ball Grid Array) package designated YFP, with dimensions 0.79 mm × 0.79 mm and 0.4-mm ball pitch. This is confirmed in the Package Option Addendum (page ADD-1) and Section 3 (Device Information) of the SCES603K datasheet, distinguishing it from 5-pin variants like YZPR or DPWR.
