HIGH SPEED CMOS TIMER

GENERAL DESCRIPTION

APPLICATIONS

• High speed one-shot (monostable)

pulse generation

• Precision timing

• Sequential timing

• Long delay timer

• Pulse width and pulse position

modulation

• Missing pulse detector

• Frequency divider

TheALD555timerisahighperformancemonolithictimingcircuitbuiltwith

advanced silicon gate CMOS technology. It offers the benefits of high

input impedance, thereby allowing smaller timing capacitors and longer

timing cycle; high speed, with typical cycle time of 500ns; low power

dissipation for battery operated environment; reduced supply current

spikes, allowing smaller and lower cost decoupling capacitors. It is

capable of producing accurate time delays and oscillations in both

monostable and astable operation. It operates in the one-shot (mono-

stable) mode or 50% duty cycle free running oscillation mode with a single

resistor and one capacitor. The inputs and outputs are fully compatible

with CMOS, NMOS or TTL logic.

PIN CONFIGURATION

There are three matched internal resistors (approximately 200KΩ each)

that set the threshold and trigger levels at two-thirds and one-third

respectively of V These levels can be adjusted by using the control

terminal (pin 5). When the trigger input is below the trigger level, the

output is in the high state and sourcing 2mA. When threshold input is

above the threshold level at the same time the trigger input is above the

trigger level, the internal flip-flop is reset, the output goes to the low state

andsinksupto10mA. Theresetinputoverridesallotherinputsandwhen

it is active (reset voltage less than 1V), the output is in the low state.
