HCF40110B Datasheet PDF - ST Microelectronics

●DESCRIPTION

●HCF40110B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP package. HCF40110B is a dual-clocked up/down counter with a special preconditioning circuit that allows the counter to be clocked, via positive going inputs, up or down regardless of the states or timing (within 100 ns typ.) of the other clock line. The clock signal is fed into the control logic and Johnson counter after it is preconditioned.

●■ SEPARATE CLOCK-UP AND CLOCK-DOWN LINES

●■ CAPABLE OF DRIVING COMMON CATHODE LEDS AND OTHER DISPLAYS DIRECTLY

●■ ALLOWS CASCADING WITHOUT ANY EXTERNAL CIRCUITRY

●■ MAXIMUM INPUT CURRENT OF 1 µA AT 18 V (full package-temperature range)

●■ QUIESCENT CURRENT SPECIFIED UP TO 20V

●■ STANDARDIZED, SYMMETRICAL OUTPUT CHARACTERISTCS

●■ 5V, 10V AND 15V PARAMETRIC RATINGS

●■ INPUT LEAKAGE CURRENT

●    II= 100nA (MAX) AT VDD= 18V TA= 25°C

●■ 100% TESTED FOR QUIESCENT CURRENT

●■ MEETS ALL REQUIREMENTS OF JEDEC JESD13B "STANDARD SPECIFICATIONS FOR DESCRIPTION OF B SERIES CMOS DEVICES"
