Nexperia USA Inc. 74AHC1G08GW,125

Overview

74AHC1G08GW,125 from Nexperia is a single 2-input CMOS AND gate in TSSOP5 (SOT353-1) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, symmetrical output impedance, and specified for -40 °C to +125 °C industrial temperature range. It serves as a level-translating logic gate in mixed-voltage I/O interfaces of microcontroller peripherals and sensor signal conditioning circuits.

For engineers reviewing the 74AHC1G08GW,125 datasheet, 74AHC1G08GW,125 pinout, 74AHC1G08GW,125 application, or 74AHC1G08GW,125 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V/5 V, output drive capability (±8 mA), static input/output thresholds, and thermal derating behavior in compact TSSOP5 packaging.

Technical Context

This device implements standard positive-logic AND functionality with fully buffered CMOS inputs and push-pull outputs. Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V logic domains and 5 V systems without external level shifters.

Propagation delay is characterized across VCC = 3.0–3.6 V (typ. 4.6 ns @ CL = 15 pF) and VCC = 4.5–5.5 V (typ. 3.2 ns @ CL = 15 pF), with balanced tPLH/tPHL performance and 0.5×VCC switching thresholds referenced to GND.

FAQ

What is the maximum allowable input voltage on pins A or B when VCC = 3.3 V?

The 74AHC1G08GW,125 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When powered from 3.3 V, pins A and B may safely accept 5 V logic signals without damage or functional degradation, enabling direct connection to higher-voltage peripherals without external protection components.

Does this device support true bidirectional level translation?

No. The 74AHC1G08GW,125 is a unidirectional AND gate with fixed input and output roles. While its overvoltage-tolerant inputs allow it to translate higher-voltage signals into a lower-VCC domain, it cannot pass signals from output back to inputs or function as a bus switch. Bidirectional translation requires dedicated level-shifter ICs or passive resistor-based solutions.

How does thermal derating affect power dissipation in the TSSOP5 package?

For the SOT353-1 (TSSOP5) package, total power dissipation is rated at 250 mW up to 74 °C ambient. Above that temperature, P_tot derates linearly at 3.3 mW/K - meaning at 100 °C ambient, maximum allowable power drops to 167 mW. This must be accounted for in thermally constrained enclosures or high-power-density layouts.

Can this AND gate be used to combine two clock signals?

No. Combining clock signals with an AND gate introduces metastability, duty-cycle distortion, and potential glitches due to unequal propagation delays and phase misalignment. This device is intended for static or slow-changing control logic, not clock domain merging. Use dedicated clock multiplexers or PLL-based solutions for clock signal routing.
