DESCRIPTION
FEATURES
■ Max. propagation delay of 3.7ns
■ IEE min. of –37mA
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.
An internal reference voltage generator provides VBB for
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.
The VTTL and VEE power may be applied in either order.
■ TTL outputs
■ Extended supply voltage option:
VEE = –4.2V to –5.5V
■ 25% faster than National's 325
■ Differential inputs with built-in offset
■ Voltage and temperature compensation for improved
noise immunity
■ VBB output for single-ended use
■ Internal 75KΩ input pull-down resistors
■ Function and pinout compatible with Fairchild F100K
■ Available in 28-pin PLCC package
