1 / 13 page MOTOROLA CMOS LOGIC DATA 1 MC14536B Programmable Timer The MC14536B programmable timer is a 24–stage binary ripple counter with 16 stages selectable by a binary code. Provisions for an on–chip RC oscillator or an external clock are provided. An on–chip monostable circuit incorporating a pulse–type 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. • 24 Flip–Flop Stages — Will Count From 20 to 224 • Last 16 Stages Selectable By Four–Bit Select Code • 8–Bypass Input Allows Bypassing of First Eight Stages • Set and Reset Inputs • Clock Inhibit and Oscillator Inhibit Inputs • On–Chip RC Oscillator Provisions • On–Chip Monostable Output Provisions • Clock Conditioning Circuit Permits Operation With Very Long Rise and Fall Times • Test Mode Allows Fast Test Sequence • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low–power TTL Loads or One Low–power Schottky TTL Load Over the Rated Temperature Range MAXIMUM RATINGS* (Voltages Referenced to VSS) Symbol Parameter Value Unit VDD DC Supply Voltage – 0.5 to + 18.0 V Vin, Vout Input or Output Voltage (DC or Transient) – 0.5 to VDD + 0.5 V Iin, Iout Input or Output Current (DC or Transient), per Pin ± 10 mA PD Power Dissipation, per Package† 500 mW Tstg Storage Temperature – 65 to + 150 _C TL Lead Temperature (8–Second Soldering) 260 _C * Maximum Ratings are those values beyond which damage to the device may occur. †Temperature Derating: Plastic “P and D/DW” Packages: – 7.0 mW/ _C From 65_C To 125_C Ceramic “L” Packages: – 12 mW/ _C From 100_C To 125_C BLOCK DIAGRAM STAGES 9 THRU 24 Q 24 Q 23 Q 22 Q 21 Q 20 Q 19 Q 18 Q 17 Q 16 Q 15 Q 14 Q 13 Q 12 Q 11 Q 10 Q 9 DECODER MONOSTABLE MULTIVIBRATOR DECODE OUT 13 MONO–IN 15 D 12 C 11 B 10 A 9 VDD = PIN 16 VSS = PIN 8 STAGES 1 THRU 8 8 BYPASS SET RESET CLOCK INH. 7 2 1 6 5 OUT2 4 OUT1 3 IN1 OSC.
