Product details
Overview
SN74AUP2G240DQER from Texas Instruments is a dual 3-state buffer/driver IC optimized for low-power, 3.3-V operation in memory address and bus interface applications. It features two independent noninverting buffers, each with separate 3-state output control (1OE, 2OE), operates across 0.8 V to 3.6 V supply range, delivers 4.7 ns max propagation delay at 3.3 V, and supports Ioff partial-power-down mode.
For engineers reviewing the SN74AUP2G240DQER datasheet, SN74AUP2G240DQER pinout, SN74AUP2G240DQER application, or SN74AUP2G240DQER equivalent, this page provides verified pin mapping for the X2SON-8 (DQE) package, confirmed switching characteristics at multiple VCC and load conditions, Ioff behavior under power-down, and real-world use cases in point-to-point bus driving and mixed-voltage signal translation.
Technical Context
The SN74AUP2G240DQER implements two independent noninverting buffer channels, each with dedicated 3-state enable inputs (1OE, 2OE) that place the corresponding output (1Y, 2Y) in high-impedance state when asserted high. Its AUP logic family ensures ultra-low static current (≤0.9 mA max ICC) and dynamic power consumption (Cpd = 4.3 pF typ at 3.3 V).
It supports mixed-mode signal operation via 3.6-V tolerant I/Os, maintains valid logic thresholds across 0.8–3.6 V VCC, and includes robust ESD protection (2000-V HBM, 1000-V CDM) and latch-up immunity (>100 mA per JESD 78 Class II). The Ioff circuit actively disables outputs during partial power-down to prevent backflow current.
Key Specifications

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 |
|---|---|---|---|
| SN74LVC2G240DQER | Higher ICC (max 10 µA vs. 0.9 mA), faster tpd (3.8 ns @ 3.3 V), but no Ioff support. | Lacks partial-power-down capability - unsuitable for systems requiring live-bus isolation during rail shutdown. | Select when lowest possible propagation delay is prioritized over Ioff and ultra-low static power. |
| SN74AUP2G125DQER | Same AUP family, identical VCC range and Ioff, but offers noninverting 3-state buffer with active-low enable (1G, 2G). | Requires inverted enable logic; pinout differs (G pins replace OE pins), necessitating PCB layout change. | Choose only if system control logic naturally generates active-low enables and board revision allows pinout adaptation. |
Compared with SN74LVC2G240DQER and SN74AUP2G125DQER, the SN74AUP2G240DQER uniquely balances nanosecond-scale timing, sub-mA static current, and robust Ioff - making it optimal for battery-constrained, multi-rail embedded systems where both power efficiency and domain isolation are mandatory.

FAQ
What is the maximum propagation delay of the SN74AUP2G240DQER at 3.3 V?
The SN74AUP2G240DQER has a maximum propagation delay (tpd) of 4.7 ns at VCC = 3.3 V ± 0.3 V with CL = 15 pF, as specified in the official TI datasheet SCES760B. This value applies across the full operating temperature range (–40°C to +85°C) and represents worst-case timing for design margining in high-speed memory or bus applications.
Does the SN74AUP2G240DQER support partial-power-down operation?
Yes, the SN74AUP2G240DQER fully supports partial-power-down via its Ioff feature. When VCC = 0 V, the Ioff circuit disables both outputs (1Y and 2Y), preventing current backflow from live inputs or outputs - a critical capability for hot-swap systems and multi-rail power sequencing. This behavior is tested and guaranteed per datasheet specifications.
What package type is used for the SN74AUP2G240DQER?
The SN74AUP2G240DQER uses the X2SON-8 (DQE) package: a 1.4 mm × 1.2 mm, 0.4 mm maximum height, no-lead surface-mount package with an exposed thermal pad. It features NIPDAUAG lead finish, MSL Level-1 rating, and is optimized for high-density PCB layouts in space-constrained portable devices.
Can the SN74AUP2G240DQER interface between 1.8-V and 3.3-V logic domains?
Yes, the SN74AUP2G240DQER supports mixed-voltage operation: its I/Os are 3.6-V tolerant regardless of VCC, and its input thresholds scale with VCC (e.g., VIH = 0.65×VCC at 1.1–1.95 V). When powered at 1.8 V, it reliably accepts 3.3-V inputs and drives 3.3-V loads - eliminating external level shifters in many point-to-point interfaces.
What is the input capacitance of the SN74AUP2G240DQER?
The SN74AUP2G240DQER has a typical input capacitance (Ci) of 1.5 pF, measured at VI = VCC or GND. This low value minimizes loading on upstream drivers and preserves signal edge rate in high-frequency or fan-out-critical applications such as clock distribution and memory address buffering.
