TC74HC193AP/AF
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC193AP, TC74HC193AF
Synchronous Up/Down Binary Counter
The TC74HC193A are high speed CMOS SYNCHRONOUS 4-BIT UP/DOWN COUNTER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
They have a clear input (CLR), a load input ( LOAD ), load data inputs (A~D), two clock inputs (COUNT UP, COUNT DOWN), four count data outputs (QA~QD), and other outputs ( CARRY , BORROW ).
CLEAR is active high and forces QA thru QD outputs low independent of the other inputs.
CARRY and BORROW outputs are provided in order to make a cascade connection without external circuitry.
