TS555CN

Overview

The TS555CN is a single-channel CMOS timer manufactured by STMicroelectronics, designed as a low-power alternative to standard bipolar timers. It operates within a supply voltage range of +2 V to +16 V and supports frequencies up to 2.7 MHz. The device features a typical supply current of 110 μA at 5 V, significantly lower than bipolar counterparts. It provides high input impedance (10^12 Ω) and output compatibility with TTL, CMOS, and logic MOS families. Packaged in an 8-pin DIP format, it ensures accurate time delays in monostable mode or programmable oscillations in astable mode.

Feature Summary

• Low power consumption: 110 μA typ at VCC = 5 V
• High maximum astable frequency of 2.7 MHz
• Pin-to-pin functionally-compatible with bipolar NE555
• Wide voltage range: +2 V to +16 V

Applications

• Time delay generation
• Programmable oscillator circuits
• Logic clock pulse generation

Part Context

The TS555CN belongs to the TS555 series of single-channel CMOS timers. This series is engineered for applications requiring reduced power consumption and higher frequency operation compared to traditional bipolar 555 timers. The 'C' suffix typically denotes commercial temperature range performance, while 'N' indicates the PDIP-14 package variant for dual channels in the broader family context, though specific TS555CN documentation confirms the 8-DIP package for this single-channel part.
