TRANSLATOR
FEATURES
DESCRIPTION
■ Max. propagation delay of 1.4ns
■ IEE min. of –70mA
The SY100S324 is a hex translator designed to convert
TTL logic levels to 100K ECL levels. The inputs are TTL
compatible with differential outputs that can either be
used as an inverting/non-inverting translator or as
differential line drivers. A common Enable (E), when LOW,
holds all inverting outputs HIGH and holds all non-
inverting outputs LOW.
■ Industry standard 100K ECL levels
■ Extended supply voltage option:
VEE = –4.2V to –5.5V
■ Differential outputs
When used in the differential mode, due to its high
common mode rejection, it overcomes voltage gradients
between the TTL and ECL ground systems. The VEE and
VTTL power may be applied in either order.
■ Voltage and temperature compensation for improved
noise immunity
■ Internal 75KΩ input pull-down resistors
■ Twice as fast as Fairchild’s 324
■ Function and pinout compatible with Fairchild F100K
PIN CONFIGURATIONS
■ Available in 24-pin CERPACK and 28-pin PLCC
