DESCRIPTION

· Precision timing circuits capable of producing accurate time delays or oscillation.

· Operates in astable or monostable mode with adjustable duty cycle.

· Timing controlled by external resistor and capacitor network.

· TTL-compatible output can sink or source up to 200mA.

· Threshold and trigger levels are typically two-thirds and one-third of VCC, respectively.

· Reset input can override all other inputs to initiate a new timing cycle.

FEATURES

· Timing range from microseconds to hours.

· Independent control of frequency and duty cycle in astable mode.

· Compatible with TTL inputs at 5V supply.

· Operation specified for supplies from 5V to 15V.

· On products compliant to MIL-PRF-38535, all parameters are tested unless otherwise noted.

APPLICATIONS

· Fingerprint biometrics.

· Iris biometrics.

· RFID readers.
