Product details
Overview
SN74AUC2G240YZPR from Texas Instruments is a dual 1-bit noninverting buffer/driver with independent 3-state outputs, designed for sub-1.8-V mixed-signal bus interfacing. It operates from 0.8 V to 2.7 V, delivers ±8 mA drive at 1.8 V, achieves 1.8 ns max propagation delay, and features Ioff partial-power-down support - enabling use in low-voltage memory address drivers and clock distribution networks.
For engineers reviewing the SN74AUC2G240YZPR datasheet, SN74AUC2G240YZPR pinout, SN74AUC2G240YZPR application, or SN74AUC2G240YZPR equivalent, key selection criteria include its NanoFree™ YZP package footprint, 1.8-V optimized timing, 3.6-V I/O tolerance, and guaranteed high-impedance state during power sequencing.
Technical Context
This device implements two independent noninverting buffers, each with dedicated output-enable (OE) control. Logic operation follows standard positive-logic 3-state behavior: OE low enables data pass-through (A → Y); OE high forces output into high-impedance. No internal inversion or latching is present.
It integrates Ioff circuitry to disable outputs during partial power-down, preventing backflow current when VCC = 0 V while inputs remain biased. The design supports sub-1-V operation but is characterized and optimized specifically for 1.65–1.95 V VCC range per TI SCES534C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - supports ultra-low-voltage systems down to 0.8 V, with full functionality guaranteed at 1.65–1.95 V |
| Max tpd @ 1.8 V | 1.8 ns - enables high-speed signal buffering in compact 1.8-V logic domains without timing bottlenecks |
| Output Drive | ±8 mA @ 1.8 V - sufficient to drive 15-pF loads across PCB traces or small fanouts in dense layouts |
| Ioff Support | Yes - blocks current flow when powered down, critical for hot-plug and multi-rail system interoperability |
| IOH/VOL & IOL/VOH | VOH ≥ 1.2 V @ IOH = –8 mA, VOL ≤ 0.45 V @ IOL = 8 mA - ensures robust noise margins in 1.8-V CMOS interfaces |
| 3.6-V I/O Tolerance | Yes - allows safe connection to 3.3-V or 2.5-V signals without level shifters in mixed-voltage buses |
| ICC Quiescent | 10 µA @ 1.8 V - minimizes static power in always-on subsystems such as wake-up logic or standby buffers |
Pinout & Package
NanoFree™ WCSP (YZP) 8-bump die-size ball grid array package - 1.2 mm × 1.6 mm footprint, 0.4-mm pitch, bottom-side solder bumps, Pb-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage return path |

Applications
| Memory Address Buffering | Low-Voltage Clock Distribution |
|---|---|
Use Scenario: Driving address lines between a 1.8-V microcontroller and a 1.8-V parallel SRAM or flash memory. IC Role / Device Role / Timing Role: Noninverting 3-state buffer isolating MCU address bus from memory; enables bidirectional bus sharing via OE control. Use Value: Eliminates need for discrete level shifters while maintaining <2-ns propagation delay - preserves setup/hold timing margins in high-speed memory access cycles. |
Use Scenario: Distributing a 1.8-V system clock to multiple low-power peripherals with independent enable control. IC Role / Device Role / Timing Role: Dual-channel clock buffer with separate OE pins - allows selective clock gating per peripheral without skew-inducing fanout splitting. Use Value: ±8-mA drive capability sustains signal integrity across 2–3 cm PCB traces; sub-2-ns tpd prevents clock phase degradation in tightly timed subsystems. |
| Hot-Swappable I/O Expansion | Mixed-Voltage Bus Interface |
Use Scenario: Interfacing a removable 1.8-V I/O expansion module to a mainboard operating at 3.3 V. IC Role / Device Role / Timing Role: Voltage-tolerant buffer enabling safe insertion/removal - Ioff prevents backfeed when module VCC is unpowered. Use Value: Guarantees no current flows from mainboard I/O lines into unpowered module - satisfies JEDEC JESD78 latch-up immunity requirements (>100 mA). |
Use Scenario: Bridging a 1.8-V FPGA I/O bank to legacy 2.5-V or 3.3-V sensors or communication ICs. IC Role / Device Role / Timing Role: Level-tolerant interface buffer - accepts 2.5-V inputs while powered at 1.8 V, drives 2.5-V loads directly. Use Value: Removes need for discrete voltage translators or resistive dividers - reduces BOM count and layout area in heterogeneous voltage systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUC2G125YZPR | Noninverting buffer with same YZP package, VCC range, and drive strength - differs only in input logic polarity (no inversion) | Same functional role; used where signal polarity must be preserved without inversion | Select SN74AUC2G125YZPR when identical buffering (not driver) behavior is required - avoids redesign if original schematic uses noninverting logic |
| SN74LVC2G240YZPR | Higher ICC (10 µA vs. 20 µA typical), slower tpd (2.5 ns vs. 1.8 ns @ 1.8 V), wider VCC range (1.65–5.5 V) | Better suited for 3.3-V or 5-V mixed-voltage systems where 1.8-V speed is not critical | Choose SN74LVC2G240YZPR only when broader voltage compatibility outweighs need for sub-2-ns timing - not drop-in for SN74AUC2G240YZPR in 1.8-V high-speed paths |
Compared with SN74AUC2G240YZPR, SN74AUC2G125YZPR offers identical performance and packaging with noninverting-only logic, while SN74LVC2G240YZPR trades speed and quiescent power for wider voltage flexibility - making it suitable for less timing-critical, multi-rail applications.

FAQ
What is the maximum recommended operating voltage for SN74AUC2G240YZPR?
The absolute maximum VCC rating for SN74AUC2G240YZPR is 3.6 V, but TI specifies its recommended operating range as 0.8 V to 2.7 V. For optimal timing and drive performance, it is designed specifically for 1.65–1.95 V operation - exceeding 2.7 V risks parametric degradation or reliability impact, even if within absolute limits. Always refer to SCES534C Section 6.1 for derating guidance.
Does SN74AUC2G240YZPR support true bidirectional data flow?
No, SN74AUC2G240YZPR is a unidirectional noninverting buffer - data flows only from A input to Y output per channel. It does not contain internal direction control or bus transceiver logic. Bidirectional operation requires external OE coordination and separate transmit/receive paths; SN74AUC2G240YZPR serves only as a controlled one-way driver with 3-state output disable.
Can SN74AUC2G240YZPR be used without external pull-up resistors on OE pins?
Yes - SN74AUC2G240YZPR OE inputs are CMOS-compatible and do not require pull-ups for basic logic operation. However, TI recommends tying OE to VCC via a pull-up resistor during power-up/down to guarantee high-impedance state before VCC stabilizes. The minimum resistor value depends on the driver's sink capability; see SCES534C Section 8.1 for calculation guidance.
Is the YZP package of SN74AUC2G240YZPR compatible with standard reflow profiles?
Yes - SN74AUC2G240YZPR's NanoFree™ YZP package is rated MSL Level-1 with unlimited floor life and peak reflow temperature of 260 °C. It complies with IPC/JEDEC J-STD-020 and supports standard lead-free reflow profiles. Board layout must follow TI's DSBGA land pattern guidelines (SLYA022) to ensure reliable solder joint formation and mechanical stability.
How does the Ioff feature of SN74AUC2G240YZPR protect system-level interfaces?
The Ioff circuitry in SN74AUC2G240YZPR actively disables all outputs when VCC = 0 V, blocking current flow from live inputs (e.g., 1.8-V or 3.3-V signals) into the unpowered device. This prevents damaging back-current paths in partial-power-down scenarios - satisfying JESD78 Class II latch-up immunity (>100 mA) and enabling safe hot-swap operation in modular electronics systems using SN74AUC2G240YZPR.
