74ACT08MTR

Overview

The 74ACT08MTR is a quad 2-input AND gate manufactured using sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a supply voltage range of 4.5V to 5.5V, featuring a typical propagation delay of 4.5ns at VCC = 5V. The device provides symmetrical output impedance with minimum source/sink currents of 24mA. It includes protection circuits offering 2kV ESD immunity and is compatible with TTL outputs (VIH min 2V, VIL max 0.8V). Quiescent supply current is maximized at 2μA at 25°C.

Procurement Notes

Verify the specific package suffix matches the required form factor: 'M' indicates SO-14, while 'B' denotes DIP-14. Confirm that the 'TR' suffix corresponds to tape-and-reel packaging if reel delivery is necessary. Ensure the component meets the specified operating temperature range of -55°C to 125°C for your application environment.

Selection Notes

Select this component when interfacing high-speed CMOS logic with TTL-compatible systems requiring precise voltage level matching. The symmetrical output drive capability and balanced propagation delays make it suitable for timing-critical digital circuits. Verify that the 4.5V to 5.5V operating voltage aligns with the system power rails.
