Overview
The LB8555 is a delay time generator IC capable of gener-
ating exact timing pulses. Both trigger pin and reset pin are
provided for various uses such as monostable multivibrator,
astable multivibrator. The output circuit is capable of ap-
plying 200mA sink/source current. Output is interfaceable
to TTL. This IC is usable as a replacement for Signetics-
made NE555.
Features
Timing time settable from several
μs. to several hours.
Monostable multivibrator consisting of R=1, C=1 ; astable
multivibrator consisting of R=2, C=1.
Adjustable duty cycle of pulse.
200mA sink/source current for driving external load.
Applications
Delay time generator (monostable multivibrator).
Sequence timer.
Pulse generator (astable multivibrator).
DC-DC converter.
Pulse width modulator.
