M74HCT541RM13TR

Overview

The M74HCT541RM13TR is an octal bus buffer with 3-state outputs, fabricated using silicon gate C2MOS technology. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -55°C to +125°C. The device features high-speed performance with a typical propagation delay of 14ns at VCC = 4.5V. It provides symmetrical output impedance with |IOH| = IOL = 6mA (min) and low power dissipation with ICC = 4μA (max) at TA=25°C. The package type is SOP-20.

FAQ

How does the 3-state control gate operate?

The 3-state control gate operates as a two-input AND such that if either G1 or G2 is high, all eight outputs are in the high impedance state.

What is the purpose of the specific pinout arrangement?

The M74HCT541 offers a pinout having inputs and outputs on opposite sides of the package to enhance PC board layout.
