Programmable Timer
The MC14536B programmable timer is a 24âstage binary ripple
counter with 16 stages selectable by a binary code. Provisions for an
onâchip RC oscillator or an external clock are provided. An onâchip
monostable circuit incorporating a pulseâtype 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
⢠24 FlipâFlop Stages â Will Count From 20 to 224
⢠Last 16 Stages Selectable By FourâBit Select Code
⢠8âBypass Input Allows Bypassing of First Eight Stages
⢠Set and Reset Inputs
⢠Clock Inhibit and Oscillator Inhibit Inputs
⢠OnâChip RC Oscillator Provisions
⢠OnâChip 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 LowâPower TTL Loads or One LowâPower
Schottky TTL Load over the Rated Temperature Range
⢠PbâFree Packages are Available*

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
highâimpedance 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 outputs must be left open.
