DESCRIPTION

The M54/74HC593 is a high speed CMOS 8 BIT

silicon gate C²MOS technology. It has the same

high speed performance of LSTTL combined with

true CMOS low power consumption.

The M54/74HC593 consists of a parallel input, 8 bit

storage register feeding an8bitbinary counter. Both

the register and the counter have individual positive

edge-triggered clock. Inaddition, the counter has di-

rectload and clear functions. Expansion iseasily ac-

complished by connecting RCO of first stage to the

count enable CCKEN, of the second stage etc.

The M54/74HC593 comes in a 20 pin package and

has 3 state I/O, which provides parallel counter out-

puts.

NC =

No Internal

Connection

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
