M74HCT160 SYNCHRONOUS PRESETTABLE 4-BIT COUNTER s s s s s s HIGH SPEED : fMAX = 50 MHz (TYP.) at VCC = 4.5V LOW POWER DISSIPATION: ICC =4A(MAX.) at TA=25C COMPATIBLE WITH TTL OUTPUTS : VIH = 2V (MIN.) VIL = 0.8V (MAX) SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN) BALANCED PROPAGATION DELAYS: tPLH tPHL PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 160 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HCT160B1R M74HCT160M1R T&R M74HCT160RM13TR M74HCT160TTR DESCRIPTION The M74HCT160 is an high speed CMOS SYNCHRONOUS BCD DECADE PRESETTABLE COUNTER fabricated with silicon gate C2MOS technology. The CLOCK input is active on the rising edge. Both LOAD and CLEAR inputs are active LOW. Presetting is synchronous on the rising edge of the clock, the function is cleared asynchronously. Two enable inputs (TE and PE) and CARRY output are provided to enable easy cascading of counters, which facilities easy implementation of N-bit counters without using external gates. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
