FEATURES
s 700MHz min. count frequency s Extended 100E VEE range of –4.2V to –5.5V s 1000ps CLK to Q, TC s Internal, gated TC feedback s 8 bits wide s Fully synchronous counting and TC generation s Asynchronous Master Reset s Fully compatible with industry standard 10KH, 100K I/O levels s Internal 75KΩ input pulldown resistors s Fully compatible with Motorola MC10E/100E016 s Available in 28-pin PLCC package DESCRIPTION
Architecture and operation are the same as the Motorola MC10H016 in the MECL 10KH family, extended to 8 bits, as shown in the logic diagram. When TCLD is HIGH, the TC feedback causes the counter to automatically reload upon TC = LOW, thus functioning as a programmable counter.
