Texas Instruments SN74LVC2G241YZPR

Overview

SN74LVC2G241 from Texas Instruments is a dual 1-bit noninverting buffer/driver with independent 3-state outputs, designed for 1.65-V to 5.5-V V_CC operation. It delivers ±24-mA output drive at 3.3 V, achieves 4.1-ns max propagation delay, supports 5.5-V tolerant inputs, and features I_off for live insertion and partial-power-down protection. It serves as a redriver in compact digital interfaces such as memory-address buses and clock distribution paths in portable media players.

For engineers reviewing the SN74LVC2G241 datasheet, SN74LVC2G241 pinout, SN74LVC2G241 application, or SN74LVC2G241 equivalent, key selection criteria include its DSBGA-8 (YZP) package footprint, dual independent OE control (1OE active-low, 2OE active-high), 3.3-V/5-V mixed-signal interfacing capability, and guaranteed 3-state behavior during power sequencing.

Technical Context

The SN74LVC2G241 implements two independent CMOS buffer stages, each with dedicated output-enable logic: Gate 1 enables on low at 1OE, Gate 2 enables on high at 2OE. This asymmetric OE polarity allows flexible bus arbitration-e.g., one gate can be held active while the other is tri-stated without shared control logic.

Its I_off circuitry actively disables outputs when V_CC = 0 V, blocking current backflow up to ±10 µA, and input tolerance extends to 5.5 V regardless of V_CC, enabling down-translation from 5-V logic to lower-voltage domains. The device meets JESD 78 Class II latch-up immunity (>100 mA) and exceeds JESD 22 ESD ratings (±2000-V HBM, ±1000-V CDM).

Key Specifications

Pinout & Package

SN74LVC2G241YZPR uses an 8-pin DSBGA (Die Size Ball Grid Array) package measuring 1.91 mm × 0.91 mm with bottom-side ball terminations. This ultra-compact NanoFree™ package eliminates traditional leadframe and molding compound, using the silicon die itself as the mechanical structure.

FAQ

What is the function of the 1OE and 2OE pins on the SN74LVC2G241YZPR?

The 1OE pin is an active-low output enable controlling the first buffer (1A→1Y), while 2OE is active-high for the second buffer (2A→2Y). This asymmetric polarity allows independent, glitch-free bus control-e.g., holding one output active while tri-stating the other without external inverters. Both pins must be properly biased during power-up to ensure predictable 3-state behavior in the SN74LVC2G241YZPR.

Does the SN74LVC2G241YZPR support 5-V input signals when powered from 3.3 V?

Yes. The SN74LVC2G241YZPR features 5.5-V tolerant inputs, meaning 1A, 2A, 1OE, and 2OE accept voltages up to 5.5 V regardless of V_CC. When V_CC = 3.3 V, this enables direct interfacing with 5-V logic without level shifters-critical for mixed-voltage systems. This specification is guaranteed across –40°C to +85°C for the SN74LVC2G241YZPR.

What is the maximum output current drive capability of the SN74LVC2G241YZPR at 3.3 V?

The SN74LVC2G241YZPR delivers ±24 mA output drive per channel at V_CC = 3.3 V, as specified in the Electrical Characteristics table. This ensures reliable signal integrity into standard 50-Ω transmission lines or fanout to multiple CMOS inputs. Continuous output current must not exceed ±50 mA per pin or ±100 mA total for V_CC/GND, per Absolute Maximum Ratings.

How does the I_off feature protect the SN74LVC2G241YZPR during partial power-down?

The I_off circuitry in the SN74LVC2G241YZPR disables all outputs when V_CC = 0 V, limiting back-current to ±10 µA maximum. This prevents damaging current flow from live signal lines into a powered-down device-essential for hot-plug modules, battery-backed subsystems, or systems with staggered power sequencing. I_off is fully characterized per JESD 78 Class II.

What package type and dimensions does the SN74LVC2G241YZPR use?

The SN74LVC2G241YZPR uses Texas Instruments' NanoFree™ DSBGA-8 (YZP) package: a bottom-terminated, leadless die-scale array measuring 1.91 mm × 0.91 mm with 0.5-mm ball pitch. Unlike conventional packages, it eliminates leadframe and mold compound-using the silicon die as the structural element. This reduces height to 0.5 mm and minimizes parasitic inductance for high-speed performance.
