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.
