Description
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 comparison of words greater than 8-bits.
This device is useful in memory block decoding applications, where memory block enable signals must be generated from computer address information.
Features
? 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 6 V
? Low Input Current: 1 μA max
? Low Quiescent Supply Current: ICC (static) = 4 μA max (Ta = 25°C)
