100398中文资料Quad Differential ECL/TTL Translating Transceiver with Latch数据手册ONSEMI规格书

描述 Description

General Description
The 100398 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 100398 is ideal for mixed technology applications utilizing either an ECL or TTL backplane.
The direction of translation is set by the direction control pin (DIR). The DIR pin on the 100398 accepts TTL logic levels. A TTL LOW on DIR sets up the ECL pins as inputs and TTL pins as outputs. A TTL HIGH on DIR sets up the TTL pins as inputs and ECL pins as outputs.
