LM556数据手册集成电路（IC）的可编程定时器振荡器规格书PDF

描述 Description

The UTC LM556 dual monolithic circuit is a highlystable controller capable of producing accurate delaysor oscillation. The UTC LM556 is the dual of UTCNE555; timing is provided an external resistor andcapacitor for each function. The two timers operateindependently of each other, sharing only Vcc andGND. The circuits may be triggered and reset onfalling wave forms. The output structures may sink or source 200mA.

特性 Features

• High current driver capability(=200mA)
• Adjustable duty cycle
• Timing from µSec to Hours
• Temperature stability of 0.005%/°C
• TTL compatible
• Operates in both Astable and Monostable modes
