SN10KHT5538
SN10KHT5538 is Octal ECL-to-TTL Translator manufactured by Texas Instruments.
description
This octal ECL-to-TTL translator is designed to provide efficient translation between a 10KH signal environment and a TTL signal environment. This device is designed specifically to improve the performance and density of ECL-to-TTL CPU/bus oriented functions such as memory address drivers, clock drivers, and busoriented receivers and transmitters while eliminating the need for three-state overlap protection.
Two output enables, OE1 and OE2, are provided. These enable inputs are ANDed together with OE1 being ECL-patible and OE2 being TTL-patible. This offers the choice of controlling the outputs of the device from either a TTL or ECL signal environment.
The SN10KHT5538 is characterized for operation from 0°C to 75°C.
