LOW POWER OCTAL ECL/TTL BI-DIRECTIONAL TRANSLATOR WITH

LATCH

General Description

The F100328 is an octal latch bi-directional translator designed to convert TTL logic

levels to 100K ECL logic levels and vice versa. The direction of this translation is

determined by the DIR input. A LOW on the output enable input (OE) holds the ECL outputs

in a cut-off state and the TTL outputs at a high impedance level. A HIGH on the latch

enable input (LE) latches the data at both inputs even though only one output is enabled

at the time. A LOW on LE makes the F100328 transparent. The cut-off state is designed to

be more negative than a normal ECL LOW level. This allows the output emitter-followers to

turn off when the termination supply is -2.0V, presenting a high impedance to the data

bus. This high inpedance reduces termination power and prevents loss of low state noise

margin when several loads share the bus.

The F100328 is designed with FAST TTL output buffers, featuring optimal DC drive and

capable of quickly charging and discharging highly capacitive loads. All inputs have 50K

ohm pull-down resistors.
