The SN54HC590A is an 8-bit binary counter that feeds an 8-bit storage register, featuring parallel outputs. This device from Texas Instruments operates with a VCC range of 2V to 6V and has a typical propagation delay of 14 ns. It offers high-current 3-state parallel register outputs capable of driving up to 15 LSTTL loads.
The counter has separate clock inputs for the binary counter and the storage register, with both being positive-edge triggered. It includes direct clear (CCLR) and count-enable (CCKEN) inputs for the binary counter, and a ripple-carry output (RCO) for cascading stages. The device consumes low power, with a maximum I CC of 80 µA and a low input current of 1 µA maximum.
Packaged in a 16-pin CDIP, the SN54HC590AJ is rated for a wide operating temperature range of -55°C to 125°C, making it suitable for military and industrial applications. Expansion for larger count chains is easily achieved by connecting the RCO output of one stage to the CCKEN input of the next.
