MC10E137, MC100E137
5 V ECL 8‐Bit Ripple Counter
Description
The MC10E/100E137 is a very high speed binary ripple counter. The
two least significant bits were designed with very fast edge rates while
the more significant bits maintain standard ECLinPS™ output edge rates. This allows the counter to operate at very high frequencies while maintaining a moderate power dissipation level.

The device is ideally suited for multiple frequency clock generation
as well as a counter in a high performance ATE time measurement
board.
Both asynchronous and synchronous enables are available to
maximize the device’s flexibility for various applications. The asynchronous enable input, A_Start, when asserted enables the counter while overriding any synchronous enable signals.
