General Description

The 100397 is a quad latched transceiver designed to convert TTL logic levels to differential F100K ECL logic levels and vice versa. This device was designed with the capability of driving a differential 25Ω ECL load with cutoff capability, and will sink a 64 mA TTL load. The 100397 is ideal for mixed technology applications utilizing either an ECL or TTL backplane.
