Part Details:

HCF4516B PRESETTABLE BINARY UP/DOWN COUNTER s MEDIUM SPEED OPERATION : 8 MHz (Typ.) at 10V s SYNCHRONOUS INTERNAL CARRY PROPAGATION s RESET AND PRESET CAPABILITY s STANDARDIZED SYMMETRICAL OUTPUT CHARACTERISTICS DIP s QUIESCENT CURRENT SPECIF. UP TO 20V s 5V, 10V AND 15V PARAMETRIC RATINGS s INPUT LEAKAGE CURRENT ORDER CODES II = 100nA (MAX) AT VDD = 18V TA = 25°C PACKAGE TUBE T & R s 100% TESTED FOR QUIESCENT CURRENT DIP HCF4516BEY s MEETS ALL REQUIREMENTS OF JEDEC JESD13B "STANDARD SPECIFICATIONS FOR DESCRIPTION OF B SERIES CMOS DEVICES" level on the PRESET ENABLE line. Synchronouscascading is accomplished by connecting all clock DESCRIPTION inputs in parallel and connecting the CARRY OUT HCF4516B is a monolithic integrated circuit of a less significant stage to the CARRY IN of a fabricated in Metal Oxide Semiconductor more significant stage. HCF4516B can be technology available in DIP package. cascaded in the ripple mode by connecting all It is a PRESETTABLE BINARY UP/DOWN clock inputs in parallel and connecting the CARRY COUNTER, consists of four synchronously OUT to the clock of the next stage. If the UP/ clocked D-type flip-flops (with a gating structure to DOWN input changes during a terminal count, the provide T-type flip-flop capability) connected as a CARRY OUT must be gated with the clock, and counter. This counter can be cleared by a high the UP/DOWN input must change while the clock level on the RESET line, and can be preset to any is high. This method provides a clean clock signal binary number present on the jam inputs by a high to the subsequent counting stage. PIN CONNECTION September 2002 1/11
