DM7407

Hex Buffers with High Voltage Open-Collector Outputs

General Description

This device contains six independent gates each of which

performs a buffer function. The open-collector outputs

require external pull-up resistors for proper logical opera-

tion.

Pull-Up Resistor Equations

Where:

for all outputs tied to pull-up resistor

all inputs tied to pull-up resistor

all inputs tied to pull-up resistor

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
