Monolithic Digital IC
LB8555M
General-Purpose Timer
Overview
The LB8555M is a delay time generator IC capable of gen-
erating 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 applying 200mA sink/source current. Output is
interfaceable to TTL. This IC is usable as a replacement
for the 555 type.
