M74HC190 4 BIT SYNCHRONOUS UP/DOWN COUNTERS ■ ■ ■ ■ ■ ■ ■ HIGH SPEED : fMAX = 44 MHz (TYP.) at VCC = 6V LOW POWER DISSIPATION: ICC =4µA(MAX.) at TA=25°C HIGH NOISE IMMUNITY: VNIH = V NIL = 28 % VCC (MIN.) SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 190 DESCRIPTION The M74HC190 is an high speed CMOS 4-BIT SYNCHRONOUS UP/DOWN COUNTER fabricated with silicon gate C2MOS technology. State changes of the counter are synchronous with the LOW-to-HIGH transition of the Clock Pulse Input. An asynchronous parallel load input overrides counting and loads the data present on the DATA inputs into the flip-flops, which makes it possible to use the circuits as programmable counters. A count enable input serves as the carry/borrow DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC190B1R M74HC190M1R T&R M74HC190RM13TR M74HC190TTR input in multi-stage counters. Control input, Down/ Up, determines whether a circuit counts up or down. A MAX/MIN output and a Ripple Clock output provide overflow/underflow indication and make possible a variety of methods for generating carry/borrow signals in multi-stage counter applications. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
