Product details
Overview
SN74AUP2G241RSER from Texas Instruments is a dual 3-state buffer/driver IC in an 8-pin UQFN (RSE) package, operating from 0.8 V to 3.6 V supply. It features low static current (≤0.9 mA), 9.9 ns max propagation delay at 3.3 V, 1.5 pF typical input capacitance, and Ioff support for partial-power-down mode - enabling use in battery-powered memory-address and bus-transceiver applications.
For engineers reviewing the SN74AUP2G241RSER datasheet, SN74AUP2G241RSER pinout, SN74AUP2G241RSER application, or SN74AUP2G241RSER equivalent, key selection criteria include its ultra-low dynamic power (4.2 pF Cpd), 3.6-V I/O tolerance for mixed-voltage interfacing, and guaranteed 3-state timing performance across industrial temperature range (–40°C to 85°C).
Technical Context
The SN74AUP2G241RSER implements two independent noninverting buffers, each with separate 3-state output enable (OE) control. Its AUP logic family uses optimized CMOS design to minimize both static and dynamic power across the full 0.8–3.6 V VCC range, supporting voltage scaling in portable systems.
Each channel supports bidirectional signal flow only when enabled; outputs enter high-impedance state when OE is high (active-high enable). The Ioff circuitry blocks current flow when VCC = 0 V, preventing backfeed during partial power-down - critical for system-level power sequencing in multi-rail designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with 1.2-V, 1.8-V, 2.5-V, and 3.3-V logic domains without level shifters. |
| tpd Max | 9.9 ns at 3.3 V, CL = 15 pF - ensures sub-10 ns timing margin for point-to-point clock/data buffering up to ~50 MHz. |
| Ioff Current | ≤0.6 mA at VCC = 0 V - guarantees isolation of powered-down sections from active buses, meeting JESD78 Class II latch-up immunity. |
| Cpd | 4.2 pF typical at 3.3 V - reduces switching power by >50% vs. older low-voltage families, extending battery life in always-on subsystems. |
| Input Capacitance | 1.5 pF typical - minimizes capacitive loading on driving sources, preserving signal integrity in high-speed, high-fanout traces. |
| IOH/IOL | ±4 mA at 3 V - provides sufficient drive strength for short PCB traces and light capacitive loads without external buffering. |
Pinout & Package
SN74AUP2G241RSER is housed in an 8-pin UQFN (RSE) package, 1.55 mm × 1.55 mm, 0.6 mm max height, with wettable flank leads and exposed thermal pad. Pin 1 is marked by a corner chamfer per JEDEC MO-287.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-high output enable for Channel 1 - drives 1Y high-impedance when logic high. |
| 2 | 1A | Noninverting input for Channel 1 - passes signal to 1Y when 1OE is low. |
| 3 | 2Y | Inverting output for Channel 2 - not applicable; device is noninverting; this is 2Y (noninverting output). |
| 4 | GND | Ground reference for all internal circuitry and I/O - must be connected to system ground plane for noise immunity. |
| 5 | VCC | Primary power supply - decoupling capacitor (0.1 µF) required within 3 mm of this pin. |
| 6 | 2OE | Active-high output enable for Channel 2 - independent control allows staggered bus access. |
| 7 | 1Y | Noninverting output for Channel 1 - high-impedance when 1OE = high, else mirrors 1A. |
| 8 | 2A | Noninverting input for Channel 2 - electrically isolated from Channel 1 for dual-bus isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 mA max across full VCC range - extends runtime in coin-cell or energy-harvesting systems. |
| 3.6-V tolerant I/O | Supports mixed-mode operation with 5-V legacy peripherals while powered from 1.8-V rails - eliminates external level translators. |
| Partial-power-down support | Ioff circuitry prevents back-current flow when VCC = 0 - essential for hot-swap and modular power architectures. |
| Low-noise switching | Overshoot/undershoot <10% of VCC - reduces EMI and avoids false triggering in adjacent sensitive analog circuits. |
Applications
| Memory Address Buffering | Low-Power Sensor Hub Interface |
|---|---|
Use Scenario: Driving address lines between a low-voltage MCU and external SRAM or flash memory in wearables. IC Role / Device Role / Timing Role: Dual-channel noninverting buffer with independent 3-state control isolates memory bus during standby.

IC Role / Device Role / Timing Role: Dual noninverting driver delivering synchronized pixel data with matched propagation delays (tpd variation <0.5 ns). Use Value: Sub-10 ns tpd and <0.5 ns channel-to-channel skew prevent color timing skew, eliminating visible banding artifacts. |
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 |
|---|---|---|---|
| SN74LVC2G241RSER | Higher ICC (max 10 µA vs. 0.9 mA), faster tpd (6.7 ns), but no Ioff support and narrower VCC range (1.65–5.5 V). | Not suitable for partial-power-down systems; requires ≥1.65 V supply - incompatible with sub-1.2-V SoCs. | Select when speed > power savings, and full-rail power is guaranteed. |
| SN74AUC2G241RSER | Optimized for 2.5-V operation; lower VCC min (0.8 V), but higher Cpd (6.5 pF) and no 3.6-V I/O tolerance. | Limited to single-rail 2.5-V systems; cannot interface safely with 3.3-V peripherals without clamping. | Select only for fixed 2.5-V designs where lowest possible tpd (3.8 ns) is critical. |
Compared with SN74LVC2G241RSER and SN74AUC2G241RSER, the SN74AUP2G241RSER uniquely balances ultra-low static power, wide VCC scalability, and robust Ioff protection - making it the sole choice for battery-constrained, multi-voltage, hot-pluggable embedded systems.

FAQ
What is the maximum operating frequency supported by SN74AUP2G241RSER?
The SN74AUP2G241RSER does not specify a maximum clock frequency in its datasheet. Instead, timing is characterized by propagation delay (tpd ≤ 9.9 ns at 3.3 V, CL = 15 pF) and enable/disable times (ten/tdis ≤ 5.8 ns / 4.6 ns). For reliable point-to-point signaling, designers typically limit data rates to ≤50 MHz to maintain timing margins - verified via setup/hold analysis using the published switching characteristics tables in the SCES761B datasheet for SN74AUP2G241RSER.
Does SN74AUP2G241RSER support hot insertion or live board swapping?
Yes, SN74AUP2G241RSER supports hot insertion through its Ioff feature: when VCC = 0 V, the Ioff circuitry disables all I/O terminals, limiting current flow to ≤0.6 mA even if inputs/outputs are driven externally. This prevents damaging back-current into a powered-down system - a requirement for hot-swap compliance in modular industrial and telecom equipment using SN74AUP2G241RSER as a bus interface buffer.
Can SN74AUP2G241RSER drive a 50-pF load reliably?
While SN74AUP2G241RSER is characterized up to 30 pF (tpd ≤ 8.6 ns at 3.3 V), driving 50 pF exceeds its validated test conditions. At CL = 50 pF, propagation delay increases nonlinearly - estimated >15 ns - and edge rate degrades, raising risk of timing violations or increased EMI. For 50-pF loads, TI recommends adding series termination or selecting a higher-drive device; SN74AUP2G241RSER remains optimal for ≤30-pF point-to-point routing.
Is the RSE package of SN74AUP2G241RSER RoHS-compliant and lead-free?
Yes, SN74AUP2G241RSER in the RSE (UQFN) package is RoHS-compliant and lead-free, with NIPDAUAG (nickel-palladium-gold over silver) terminal finish. It carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified for peak reflow temperatures up to 260°C - fully compatible with standard lead-free PCB assembly processes per J-STD-020.
How does SN74AUP2G241RSER differ from SN74AUP2G125RSER?
SN74AUP2G241RSER features active-high output enables (1OE, 2OE), while SN74AUP2G125RSER uses active-low enables (1G, 2G). Both share identical electrical specs (VCC range, tpd, Cpd, Ioff), pinout, and package. The functional difference is purely logic polarity: SN74AUP2G241RSER asserts 3-state when OE = high; SN74AUP2G125RSER asserts 3-state when G = low - requiring corresponding firmware or upstream logic inversion to substitute one for the other.
