■Internal 75KΩ input pull-down resistors
в– Function and pinout compatible with Fairchild F100K
в– Available in 28-pin PLCC package 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 …
