8-BIT SYNCHRONOUS
BINARY UP COUNTER
1
presettable and cascadable 8-bit binary counters designed
for use in new, high-performance ECL systems. 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.
the TCLD (terminal count load) pin. When TCLD is LOW,
the TC feedback is disabled and counting proceeds
continuously, with TC going LOW to indicate an all-HlGH
state. When TCLD is HIGH, the TC feedback causes the
counter to automatically reload upon TC = LOW, thus
functioning as a programmable counter.
DESCRIPTION
PIN NAMES
The SY10/100E016 are high-speed synchronous,
The counters feature internal feedback of TC, gated by
