STMicroelectronics M74HC541

The M74HC541 is a non inverting buffer. The 3-STATE control gate operates as a two input AND such that if either G1 and G2 are high, all eight output are in the high impedance state. In DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC541B1R M74HC541M1R T&R M74HC541RM13TR M74HC541TTR order to enhance PC board layout the M74HC541 offer a pinout having inputs and outputs on opposite sides of the package.
