LB8555S中文资料三洋数据手册PDF规格书

Overview

The LB8555 is a delay time generator IC capable of generating 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 Signeticsmade NE555.

特性 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.
