Nat Semi DM74123N Dual Retriggerable One-Shot with Clear DIL16

Manufactured by National Semiconductor - DIL16 through hole package

DESCRIPTION

Dual Retriggerable One-Shot with Clear and Complementary Outputs

The ’123 is a dual retriggerable monostable multivibrator capable of generating output pulses from a few nano-seconds to extremely long duration up to 100% duty cycle. Each device has three inputs permitting the choice of either leading-edge or trailing edge triggering. Pin (A) is an active-low transition trigger input and pin (B) is an active-high transition trigger input. A low at the clear (CLR) input terminates the output pulse: which also inhibits triggering. An internal connection from CLR to the input gate makes
it possible to trigger the circuit by a positive-going signal on CLR as shown in the truth table.

FEATURES

• DC triggered from active-high transition or active-low transition inputs
• Retriggerable to 100% duty cycle
• Direct reset terminates output pulse
• Compensated for VCC and temperature variations
• DTL, TTL compatible
• Input clamp diodes
