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
ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ • Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range
