MC74HC540A Octal 3-State Inverting Buffer/Line Driver/Line Receiver

INPUTS A1, A2, A3, A4, A5, A6, A7, A8 (PINS 2, 3, 4, 5, 6, 7, 8, 9) * Data input pins. Data on these pins appear in inverted form on the corresponding Y outputs, when the outputs are enabled. CONTROLS OE1, OE2 (PINS 1, 19) * Output enables (active *low). When a low voltage is.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Inverting Buffer/ Line Driver/Line Receiver High Performance Silicon Gate CMOS The MC74HC540A is identical in pinout to the LS540. The device inputs are compatible with Standard CMOS outputs. External pullup resistors make them compatible with LSTTL outputs. The HC540A is an octal inverting buffer/line driver/line receiver designed to be used with 3 state memory address drivers, clock drivers, and other bus ori.

MC74HC540A Features

* inputs and outputs on opposite sides of the package and two ANDed active

* low output enables. The HC540A is similar in function to the HC541A, which has non

* inverting outputs.

* Output Drive Capability: 15 LSTTL Loads

* Outputs Directly Interface to CMOS, NMOS and TTL
