ECL-to-TTL

TRANSLATOR

DESCRIPTION

FEATURES

■ Max. propagation delay of 3.7ns

■ TTL outputs

■ Extended supply voltage option:

■ 25% faster than National's 325

■ Differential inputs with built-in offset

■ Voltage and temperature compensation for improved

noise immunity

■ Function and pinout compatible with Fairchild F100K

■ Available in 24-pin CERPACK and 28-pin PLCC

packages

The SY100S325 are hex translators for converting

100K ECL logic levels to TTL logic levels. Inputs can be

used as inverting, non-inverting or differential receivers.

single-ended operation or for use in Schmitt trigger

applications. All inputs have 75KΩ pull-down resistors.

The outputs will go LOW when the inputs are either open

or have the same potential.

When used in single-ended operation, the apparent

input threshold of the true inputs is 20mV to 40mV higher

(positive) than the threshold of the complementary inputs.
