Nexperia USA Inc. 74AHCT2G241DP-Q10H

Overview

74AHCT2G241DP-Q10H from Nexperia is an automotive-qualified dual 1-bit non-inverting buffer/line driver with independent 3-state outputs, TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 2.0–5.5 V supply range, and operation up to +125 °C - used in CAN/LIN bus interface signal conditioning and automotive body control modules.

For engineers reviewing the 74AHCT2G241DP-Q10H datasheet, 74AHCT2G241DP-Q10H pinout, 74AHCT2G241DP-Q10H application, or 74AHCT2G241DP-Q10H equivalent, key selection criteria include TTL-level input compatibility, dual independent output enables (1OE active LOW, 2OE active HIGH), 3.4 ns typical propagation delay at 5 V/15 pF, overvoltage-tolerant inputs to 5.5 V, and AEC-Q100 Grade 1 qualification for under-hood applications.

Technical Context

This device implements two independent non-inverting buffer channels, each with dedicated output enable control: 1OE (active LOW) and 2OE (active HIGH). Its TTL-input threshold (VIH ≥ 2.0 V, VIL ≤ 0.8 V) ensures direct interfacing with legacy 5 V microcontrollers without level shifting.

Each channel supports high-impedance tri-state output (Z) when its enable is deasserted, enabling bus sharing in multiplexed automotive networks. Input overvoltage tolerance to 5.5 V allows safe operation in mixed-voltage domains where input signals may exceed VCC.

FAQ

What is the maximum clock frequency supported by 74AHCT2G241DP-Q10H?

The device does not specify a maximum clock frequency because it is a combinational buffer, not a clocked element. Its usable data rate is determined by propagation delay (3.4 ns typ) and load capacitance. At 15 pF load and 5 V supply, it reliably handles digital signals up to ~150 MHz (1/(2 × tpd)), assuming clean edges and proper termination.

Can 74AHCT2G241DP-Q10H drive a 50 Ω transmission line directly?

No - its output drive strength (±8 mA) is insufficient for direct 50 Ω line driving, which typically requires >20 mA. It is designed for point-to-point or fanout-to-CMOS loads (≤50 pF). For transmission line driving, use a dedicated line driver IC or add a current-boosting buffer stage.

Is the 74AHCT2G241DP-Q10H pin-compatible with the 74AHC2G241DP-Q100?

Yes - both share identical TSSOP8 (SOT505-2) pinout and function table. The key difference is input logic type: AHCT uses TTL thresholds (VIH ≥ 2.0 V), while AHC uses CMOS thresholds (VIH ≥ 0.7×VCC). Swapping them requires verifying source logic levels meet the respective VIH/VIL requirements.

Does 74AHCT2G241DP-Q10H support hot insertion or live swapping?

No - it lacks Ioff (power-off protection) or IOZ (bus-hold) features. Applying input signals while VCC is unpowered may cause latch-up or excessive current flow through internal clamps. Always power VCC before applying inputs, and use series resistors if hot-swap operation is required.
