Nexperia USA Inc. 74AHC2G241DC-Q100H

Overview

74AHC2G241DC-Q100 from Nexperia is an automotive-qualified dual 1-bit buffer/line driver with independent 3-state outputs, CMOS-level inputs, 2.0–5.5 V supply range, and operation up to +125 °C. It supports mixed-voltage translation via overvoltage-tolerant inputs (to 5.5 V) and is used in automotive body control modules for bidirectional signal conditioning between microcontrollers and peripheral drivers.

For engineers reviewing the 74AHC2G241DC-Q100 datasheet, 74AHC2G241DC-Q100 pinout, 74AHC2G241DC-Q100 application, or 74AHC2G241DC-Q100 equivalent, key selection criteria include input voltage compatibility across rail domains, enable polarity asymmetry (1OE active LOW, 2OE active HIGH), propagation delay consistency under 125 °C, and AEC-Q100 Grade 1 qualification for under-hood deployment.

Technical Context

This device implements two independent buffer channels, each with dedicated output-enable control: 1OE (active LOW) and 2OE (active HIGH), enabling flexible bus arbitration and direction control in half-duplex interfaces. Input overvoltage tolerance (to 5.5 V) allows safe interfacing with 5 V logic while powered from 3.3 V rails.

It operates across -40 °C to +125 °C with static VIH/VIL thresholds defined for both 3.3 V and 5 V operation, and dynamic performance specified at CL = 15 pF and CL = 50 pF loads. Propagation delays remain balanced (tpd ≤ 7.5 ns @ VCC = 4.5–5.5 V, CL = 50 pF), and enable/disable times are tightly matched (ten/tdis ≤ 9.5 ns).

FAQ

What is the logic polarity of the 74AHC2G241DC-Q100 outputs?

The 74AHC2G241DC-Q100 provides non-inverting buffer functionality: 1Y follows 1A and 2Y follows 2A with no inversion. Both outputs enter high-impedance state when their respective enable inputs are deasserted - 1Y goes Hi-Z when 1OE is HIGH, and 2Y goes Hi-Z when 2OE is LOW, per the function table in Section 7 of the datasheet.

Can 74AHC2G241DC-Q100 interface a 5 V sensor with a 3.3 V microcontroller?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, allowing direct connection of 5 V sensor outputs to pins 1A or 2A while VCC = 3.3 V. The buffered outputs (1Y/2Y) swing rail-to-rail between GND and 3.3 V, safely driving the MCU's 3.3 V-tolerant inputs without external components.

How does the asymmetric enable configuration (1OE LOW-active, 2OE HIGH-active) benefit automotive designs?

This configuration enables deterministic bus arbitration: one channel can be held in Hi-Z while the other remains active, supporting master/slave handshaking in LIN or custom serial protocols. For example, 2OE (HIGH-active) can release the bus immediately upon command, while 1OE (LOW-active) holds status data until explicitly disabled - reducing collision risk in distributed ECUs.

Is thermal derating required for continuous operation at +125 °C?

Yes - total power dissipation must be derated linearly at 4.9 mW/K above +99 °C for the VSSOP8 (SOT765-1) package. At +125 °C, Ptot is reduced to 127.5 mW (250 mW − 4.9 mW/K × 26 K). Designers must verify worst-case ICC × VCC + Σ(CL × VCC² × f) stays below this limit under full-load switching conditions.
