HD74HC688 comparator equivalent, 8-bit magnitude comparator.
* High Speed Operation: tpd (P or Q to Output) = 17 ns typ (CL = 50 pF)
* High Output Current: Fanout of 10 LSTTL Loads
* Wide Operating Voltage: VCC = 2 to.
where memory block enable signals must be generated from computer address information.
Features
* High Speed Oper.
The HD74HC688 compares bit for bit two 8-bit words and indicates whether or not they are equal. The P=Q output indicates equality when it is low.
A single active low enable is provided to facilitate cascading of several packages and enable compariso.
