TS555IPT

Overview

The TS555IPT 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 +2V to +16V and supports high-frequency oscillation up to 2.7 MHz. The device features a typical supply current of 110 μA at 5V and maintains timing accuracy in both monostable and astable modes. It utilizes an 8-pin TSSOP surface-mount package and offers output compatibility with TTL, CMOS, and logic MOS standards.

Feature Summary

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

Applications

• Home, building, and city automation
• Factory automation
• Household appliances and professional equipment
• IoT for smart homes and smart cities

Procurement Notes

Verify the specific suffix 'IPT' corresponds to the TSSOP-8 package and industrial temperature grade (-40°C to +125°C) when sourcing. Confirm active status or end-of-life notifications via official ST channels, as availability varies by region and distributor.

Selection Notes

Select this component for applications requiring pin-compatible replacement of bipolar 555 timers with reduced power consumption. Ensure the design accommodates the 2V to 16V supply range and utilizes external timing components suitable for the 10^12 Ω input impedance to minimize capacitor size.

Part Context

The TS555IPT belongs to the TS555 family of single-channel CMOS timers. This series provides industry-standard functionality with enhanced performance characteristics, including lower power draw and higher operating frequencies compared to traditional bipolar counterparts like the NE555.

Replacement Considerations

The TS555 is functionally compatible with the NE555. Verify that substitute parts maintain the same TSSOP-8 footprint and electrical specifications if direct pin-for-pin replacement is required.
