74系列逻辑芯片/DM74LS123MX
General Description
The DM74LS123 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.
Features
■ DC triggered from active-HIGH transition or active-LOW
transition inputs
■ Retriggerable to 100% duty cycle
■ Compensated for VCC and temperature variations
■ Triggerable from CLEAR input
■ DTL, TTL compatible
■ Input clamp diodes
