  1. general description the HEF4520B is a dual 4-bit internally synchronous binary counter. the counter has an active high clock input (ncp0) and an active low clock input (ncp 1), buffered outputs from all four bit positions (nq0 to nq3) and an active high overriding asynchronous master reset input (nmr). the counter advances on either the low-to-h igh transition of the ncp0 input if ncp 1 is high or the high -to-low transition of the ncp 1 input if ncp0 is low. either ncp0 or ncp 1 may be used as the clock input to the counter while the other clock input may be used as a clock enable input. schmitt trigger action makes the clock input highly tolerant of slower clock rise and fall times. a high on nmr resets the counter (nq0 to nq3 = low) independent of ncp0 and ncp 1. it operates over a recommended v dd power supply range of 3 v to 15 v referenced to v ss (usually ground). unused inputs must be connected to v dd , v ss , or another input. 2. features and benefits ? tolerant of slow clock rise and fall times ? fully static operation ? 5 v, 10 v, and 15 v parametric ratings ? standardized symmetrical output characteristics ? specified from ? 40 ? c to +85 ? c ? complies with jedec standard jesd 13-b 3. ordering information HEF4520B dual binary counter rev. 6 ? 18 november 2011 product data sheet table 1. ordering information all types operate from ? 40 ? c to +85 ? c. type number package name description version HEF4520Bp dip16 plastic dual in-line pa ckage; 16 leads (300 mil) sot38-4 HEF4520Bt so16 plastic small outline packa ge; 16 leads; body width 3.9 mm sot109-1
