DESCRIPTION
s Max. propagation delay of 700ps s IEE min. of –55mA s Extended supply voltage option:
VEE = –4.2V to –5.5V s Voltage and temperature compensation for
improved noise immunity s Internal 75kΩ input pull-down resistors s 70% faster than Fairchild 300K at lower power s Function and pinout compatible with Fairchild F100K s Available in 28-pin PLCC package
The SY100S322 is an ultra-fast buffer designed for use in high-performance ECL systems. The device provides nine non-inverting buffers with single-ended outputs. The inputs on the device have 75kΩ pull-down resistors.
