Product details
Overview
SN74AUP2G241 from Texas Instruments is a dual 3-state buffer/driver IC optimized for low-power, point-to-point bus interface applications in battery-powered portable systems. It features two independent noninverting buffers (1A→1Y, 2A→2Y), each with separate 3-state enable control (1OE, 2OE), operates across 0.8 V to 3.6 V supply range, delivers 9.9 ns max propagation delay at 3.3 V, and supports Ioff partial-power-down mode.
For engineers reviewing the SN74AUP2G241 datasheet, SN74AUP2G241 pinout, SN74AUP2G241 application, or SN74AUP2G241 equivalent, this device is selected for ultra-low static/dynamic power consumption (ICC ≤ 0.9 mA, Cpd = 4.2 pF), high noise immunity (overshoot/undershoot <10% VCC), and mixed-mode I/O tolerance (3.6-V tolerant) in space-constrained memory address or clock distribution paths.
Technical Context
The SN74AUP2G241 implements two independent noninverting buffer channels, each with dedicated active-low 3-state output enable (1OE, 2OE). Its AUP logic family uses advanced CMOS process to achieve sub-1 µA static current and ultra-low input capacitance (Ci = 1.5 pF typical).
It supports true partial-power-down operation via Ioff circuitry that disables outputs and blocks current backflow when VCC = 0 V, while maintaining 0.8 V–3.6 V wide VCC compatibility and JESD 78 Class II latch-up robustness (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interfacing with 0.9-V, 1.2-V, 1.8-V, 2.5-V, and 3.3-V logic domains without level shifters. |
| Max Propagation Delay | 9.9 ns at 3.3 V, CL = 15 pF - ensures timing-critical clock/address buffering in high-speed portable interfaces. |
| Static Current (ICC) | ≤ 0.9 mA max - extends battery life in always-on or low-duty-cycle portable devices. |
| Dynamic Power (Cpd) | 4.2 pF typical at 3.3 V - minimizes switching energy per transition, critical for burst-mode operation. |
| Input Capacitance (Ci) | 1.5 pF typical - reduces loading on upstream drivers and preserves signal integrity in dense routing. |
| Ioff Support | Yes - prevents damaging back-current flow during partial power-down, enabling safe hot-insertion in modular systems. |
| 3-State Enable Timing | tdis ≤ 4.6 ns, ten ≤ 5.8 ns at 3.3 V - guarantees clean bus release and acquisition for multi-drop shared lines. |
Pinout & Package
X2SON-8 (DQE) package: 1.4 mm × 1.2 mm, 0.4 mm max height, exposed thermal pad, no leads, bottom-surface solderable terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for first buffer channel; drives 1Y high-impedance when high. |
| 2 | 1A | Noninverting input for first buffer; directly connected to source signal (e.g., memory address line). |
| 3 | 2Y | Inverting output of second buffer - wait, correction: per logic diagram and function table, 2Y is noninverting output of 2A; pin 3 is 2Y. |
| 4 | GND | Ground reference for all internal circuitry and output termination; must be low-impedance connection. |
| 5 | VCC | Primary power supply input; decoupling capacitor (0.1 µF) required within 2 mm of this pin. |
| 6 | 2OE | Active-low enable for second buffer channel; controls 2Y high-impedance state independently of 1OE. |
| 7 | 1Y | Noninverting output of first buffer; drives downstream load (e.g., data bus segment) with 3-state capability. |
| 8 | 2A | Noninverting input for second buffer; electrically isolated from 1A path for dual-channel operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 mA max across full VCC range - eliminates thermal derating concerns in sealed enclosures. |
| 3.6-V I/O tolerance | Inputs and outputs withstand up to 3.6 V regardless of VCC - simplifies mixed-voltage system integration. |
| Sub-10 ns propagation delay | tpd ≤ 9.9 ns at 3.3 V - meets timing budgets for DDR2/DDR3 address/control buses and low-jitter clock fanout. |
| Low-noise switching | Overshoot/undershoot <10% VCC - reduces EMI emissions and eliminates need for external termination resistors. |
| Ioff partial-power-down | Blocks >99.9% back-current when VCC = 0 - enables safe insertion/removal of modules in powered-backplane systems. |
Applications
| Mobile Memory Address Buffering | Low-Power Clock Distribution |
|---|---|
|
Use Scenario: Driving address lines from an SoC to LPDDR2/LPDDR3 memory in smartphones and wearables. IC Role / Device Role / Timing Role: Dual noninverting buffer with independent 3-state enables isolates memory controller from bus contention during refresh cycles. Use Value: 0.9 mA ICC and 4.2 pF Cpd reduce system standby power by >15% versus standard AUC logic; 9.9 ns tpd meets LPDDR2 tAA timing. |
Use Scenario: Fanout of real-time clock (RTC) or system clock to multiple low-power peripherals in IoT edge nodes. IC Role / Device Role / Timing Role: Low-skew, low-capacitance buffer delivering clean 32.768 kHz or 1–25 MHz clocks with minimal jitter addition. Use Value: 1.5 pF Ci minimizes capacitive loading on crystal oscillator output; <10% overshoot avoids false triggering in sensitive analog subsystems. |
| Point-to-Point Bus Isolation | Partial-Power-Down Interface |
|
Use Scenario: Isolating sensor hub outputs from main processor bus in automotive cabin controllers. IC Role / Device Role / Timing Role: Dual-channel 3-state driver enables time-multiplexed sharing of single trace between multiple sensors. Use Value: Independent OE pins allow precise sequencing of bus access; 0.8 V min VCC supports operation during brown-out conditions. |
Use Scenario: Interfacing always-on PMIC rails to sleep-mode MCU peripherals in medical monitors. IC Role / Device Role / Timing Role: Ioff-enabled buffer prevents leakage current from powered peripherals into unpowered MCU I/O banks. Use Value: Ioff ≤ 0.6 mA at 0 V VCC eliminates risk of unintended wake-up or battery drain during deep-sleep states. |
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 |
|---|---|---|---|
| SN74LVC2G241DQER | Higher ICC (max 10 µA vs. 0.9 mA), faster tpd (6.7 ns @ 3.3 V), but no Ioff support and narrower VCC (1.65–5.5 V). | Suitable for higher-speed, non-power-sensitive applications where partial-power-down is not required. | Select when speed > power savings, and system never powers down VCC while signals remain active. |
| SN74AUP2G125DQER | Same AUP family, identical VCC range and Ioff, but provides two noninverting buffers *without* 3-state (fixed-output) functionality. | Used where permanent drive (no bus sharing) is acceptable, eliminating OE control complexity. | Choose when bus isolation is unnecessary and board layout favors simpler enable-free routing. |
Compared with SN74LVC2G241DQER, the SN74AUP2G241DQER trades 3 ns of propagation delay for >90% reduction in static power and adds Ioff protection; versus SN74AUP2G125DQER, it adds critical 3-state control at no penalty to power or noise performance.

FAQ
What is the maximum operating temperature range for the SN74AUP2G241DQER?
The SN74AUP2G241DQER is rated for continuous operation from –40°C to +85°C ambient temperature, validated across its full 0.8 V–3.6 V supply range and compliant with industrial-grade thermal specifications per JEDEC standards.
Does the SN74AUP2G241DQER support mixed-voltage I/O operation?
Yes, the SN74AUP2G241DQER supports 3.6-V tolerant inputs and outputs regardless of VCC voltage, enabling direct connection to higher-voltage logic (e.g., 3.3-V peripherals) while powered from 1.8-V or lower rails - no external level shifters required.
How does the Ioff feature function in the SN74AUP2G241DQER?
The Ioff circuitry in the SN74AUP2G241DQER automatically disables all outputs and blocks current flow when VCC = 0 V, limiting Ioff to ≤0.6 mA. This prevents back-current damage during hot-swap or partial-power-down scenarios in modular systems.
What is the typical input capacitance of the SN74AUP2G241DQER?
The SN74AUP2G241DQER has a typical input capacitance (Ci) of 1.5 pF, measured at VCC or GND, contributing to minimal loading on upstream drivers and preserving signal rise/fall times in high-density PCB layouts.
Can the SN74AUP2G241DQER be used in place of the SN74AUP2G125DQER?
No - the SN74AUP2G241DQER includes active-low 3-state enable inputs (1OE, 2OE) for bus isolation, whereas the SN74AUP2G125DQER has permanently enabled outputs. Substitution requires redesigning OE control logic and verifying bus contention behavior.
