MC145041DW

The MC145041DW is one member of the MC145041 family which is designed as the programmable timer that is a 24stage binary ripple counter with 16 stages selectable by a binary code. An onchip monostable circuit incorporating a pulsetype output has been included. By selecting the appropriate counter stage in conjunction with the appropriate input clock frequency, a variety of timing can be achieved.

Features of the MC145041DW are:(1)Last 16 Stages Selectable By Four-bit Select Code; (2)8-bypass Input Allows Bypassing of First Eight Stages; (3)Set and Reset Inputs; (4)Clock Inhibit and Oscillator Inhibit Inputs; (5)On-hip RC Oscillator Provisions; (6)On-hip Monostable Output Provisions; (7)Clock Conditioning Circuit Permits Operation With Very Long Rise and Fall Times; (8)Test Mode Allows Fast Test Sequence; (9)Supply Voltage Range = 3.0 Vdc to 18 Vdc; (10)Capable of Driving Two Low-power TTL Loads or One Low-power Schottky TTL Load Over the Rated Temperature Range.

The absolute maximum ratings of the MC145041DW can be summarized as:(1)DC Supply Voltage Range:0.5 to +18.0 V;(2)Input or Output Voltage Range (DC or Transient):0.5 to VDD + 0.5 V;(3)Input or Output Current (DC or Transient) per Pin:±10 mA;(4)Power Dissipation, per Package: 500 mW;(5)Operating Temperature Range:55 to +125 °C;(6)Storage Temperature Range:65 to +150 °C;(7)Lead Temperature (8Second Soldering): 260 °C.
