1 / 12 page © Semiconductor Components Industries, LLC, 2000 August, 2000 – Rev. 4 1 Publication Order Number: MC14516B/D MC14516B Binary Up/Down Counter The MC14516B synchronous up/down binary counter is constructed with MOS P–channel and N–channel enhancement mode devices in a monolithic structure. This counter can be preset by applying the desired value, in binary, to the Preset inputs (P0, P1, P2, P3) and then bringing the Preset Enable (PE) high. The direction of counting is controlled by applying a high (for up counting) or a low (for down counting) to the UP/DOWN input. The state of the counter changes on the positive transition of the clock input. Cascading can be accomplished by connecting the Carry Out to the Carry In of the next stage while clocking each counter in parallel. The outputs (Q0, Q1, Q2, Q3) can be reset to a low state by applying a high to the reset (R) pin. This CMOS counter finds primary use in up/down and difference counting. Other applications include: (1) Frequency synthesizer applications where low power dissipation and/or high noise immunity is desired, (2) Analog–to–digital and digital–to–analog conversions, and (3) Magnitude and sign generation. • Diode Protection on All Inputs • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Internally Synchronous for High Speed • Logic Edge–Clocked Design — Count Occurs on Positive Going Edge of Clock • Single Pin Reset • Asynchronous Preset Enable Operation • Capable of Driving Two Low–Power TTL Loads or One Low–Power Schottky Load Over the Rated Temperature Range MAXIMUM RATINGS (Voltages Referenced to VSS) (Note 2.)

MC14516BFEL SOEIAJ–16 See Note 1. This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid ap- plications of any voltage higher than maximum rated voltages to this high–impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS v (Vin or Vout) v VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused out- puts must be left open. |
