Product details
Overview
SN74AUC2G34YZTR from Texas Instruments is a dual non-inverting buffer gate IC designed for ultra-low-voltage, high-speed logic interfacing in space-constrained applications. It operates from 0.8 V to 2.7 V (optimized for 1.65–1.95 V), delivers ±8 mA output drive at 1.8 V, achieves 1.6 ns max propagation delay at 1.8 V, and features Ioff support for partial-power-down mode. It is used in mobile SoC I/O bridging, low-power sensor interface buffering, and voltage-level translation between 1.8-V domains.
For engineers reviewing the SN74AUC2G34YZTR datasheet, SN74AUC2G34YZTR pinout, SN74AUC2G34YZTR application, or SN74AUC2G34YZTR equivalent, key selection criteria include sub-1-V operability, 1.6 ns tpd at 1.8 V, NanoFree™ DSBGA package footprint, Ioff-enabled power sequencing, and 3.6-V I/O tolerance for mixed-mode signal operation.
Technical Context
This device implements two independent positive-logic buffers (Y = A) with rail-to-rail output swing and CMOS-compatible input thresholds. Its architecture supports simultaneous operation across 0.8–2.7 V VCC while maintaining guaranteed switching performance down to 0.8 V.
The integrated Ioff circuitry actively disables outputs during power-down, blocking current backflow when VCC = 0 V - critical for hot-insertion and multi-rail system interoperability. Input and output structures are rated for 3.6-V absolute maximum voltage, enabling safe interfacing with higher-voltage logic without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
SN74AUC2G34YZTR uses the YZP (DSBGA) NanoFree™ package: 6-ball, 0.5-mm pitch, 1.4 mm × 1.4 mm body, 0.5-mm max height, Pb-free SnAgCu solder bumps. Pin 1 is identified by a solder-bump composition marker (• = Pb-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Y | Output of Buffer 1 | Non-inverting buffered copy of 1A; rail-to-rail CMOS output capable of ±8 mA sink/source |
| VCC | Power Supply | Single supply input for both buffers; must be decoupled locally due to high-speed switching current transients |
| 2Y | Output of Buffer 2 | Independent non-inverting output; electrically isolated from 1Y but shares same VCC/GND rails |
| 2A | Input of Buffer 2 | CMOS-compatible input with VIH/VIL thresholds scaling with VCC; accepts 0–3.6 V signals safely |
| GND | Ground Reference | Common return path for VCC and all I/O; requires low-inductance connection to minimize ground bounce |
| 1A | Input of Buffer 1 | Independent CMOS input; no internal tie to 2A; each channel operates fully autonomously |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP2G34YZPR | Lower ICC (5 µA vs. 10 µA), slower tpd (2.3 ns @ 1.8 V), same YZP package | Better suited for always-on, nanowatt standby circuits where speed is secondary to leakage minimization | Choose SN74AUP2G34YZPR only if <1.8 ns tpd is not required and ultra-low quiescent current dominates design priority |
| SN74LVC2G34DBVR | Higher VCC min (1.65 V), larger SOT-23-6 package, 3.3-V only optimized, no sub-1-V operation | Targeted at legacy 3.3-V industrial interfaces; lacks Ioff and mixed-voltage tolerance of SN74AUC2G34YZTR | Use SN74LVC2G34DBVR only in cost-sensitive, non-portable designs where 1.8-V operation and NanoFree™ size are not needed |
