The 74LVC1G123 is a single retriggerable monostable multivibrator with Schmitt trigger inputs. Output pulse width is controlled by three methods:The basic pulse is programmed by selection of an external resistor (REXT) and capacitor (CEXT).
Wide supply voltage range from 1.65 V to 5.5 V
High noise immunity
±24 mA output drive (VCC = 3.0 V)
CMOS low power consumption
DC triggered from active HIGH or active LOW inputs
Retriggerable for very long pulses up to 100 % duty factor
Direct reset terminates output pulse
Schmitt trigger on all inputs
Complies with JEDEC standard:
JESD8-7 (1.65 V to 1.95 V)
JESD8-5 (2.3 V to 2.7 V)
JESD8-B/JESD36 (2.7 V to 3.6 V)
Power-on-reset on outputs
Latch-up performance exceeds 100 mA
Direct interface with TTL levels
Inputs accept voltages up to 5.5 V
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and -40 °C to +125 °C
