100397

Quad Differential ECL/TTL Translating Transceiver

with Latch

General Description

Features

■ Differential ECL input/output structure

The 100397 is a quad latched transceiver designed to con-

vert TTL logic levels to differential F100K ECL logic levels

and vice versa. This device was designed with the capabil-

ity of driving a differential 25Ω ECL load with cutoff capabil-

ity, and will sink a 64 mA TTL load. The 100397 is ideal for

mixed technology applications utilizing either an ECL or

TTL backplane.

■ 64 mA FAST TTL outputs

■ 25Ω differential ECL outputs with cut-off

■ Bi-directional translation

■ 2000V ESD protection

■ Latched outputs

The direction of translation is set by the direction control

pin (DIR). The DIR pin on the 100397 accepts F100K ECL

logic levels. An ECL LOW on DIR sets up the ECL pins as

inputs and TTL pins as outputs. An ECL HIGH on DIR sets

up the TTL pins as inputs and ECL pins as outputs.

■ 3-STATE outputs

■ Voltage compensated operating range = −4.2V to −5.7V

A LOW on the output enable input pin (OE) holds the ECL

output 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 latch trans-

parent.

The cut-off state is designed to be more negative than a

normal ECL LOW level. This allows the output emitterfol-

lowers to turn off when the termination supply is −2.0V, pre-

senting a high impedance to the data bus. This high

impedance reduces termination power and prevents loss of

low state noise margin when several loads share the bus.

The 100397 is designed with FAST TTL output buffers,

featuring optimal DC drive and capable of quickly charging

and discharging highly capacitive loads. All inputs have

50 KΩ pull-down resistors.
