TC74HC193AP/AF/AFN
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC193AP,TC74HC193AF,TC74HC193AFN
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. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Note: xxxFN (JEDEC SOP) is not available in Japan. TC74HC193AP

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 2: 500 mW in the range of Ta = -40 to 65C. From Ta = 65 to 85C a derating factor of -10 mW/C shall be applied until 300 mW.
