Technical Details & Description

Dual 555 timer in a 14-SOIC — what you get

The STMicroelectronics TS556IDTTR packs two independent 555-type timer/oscillator circuits into a single 14-SOIC package. Each timer can be configured for monostable (one-shot), astable (free-running oscillator), or bistable (flip-flop) operation using external R-C networks. The dual layout saves board area and reduces component count compared to placing two single 555s side by side — useful when a design needs two timing channels with matched temperature tracking. Maximum oscillation frequency is 2.7 MHz. The 130 µA supply current per timer keeps quiescent load low. Supply range spans 2V to 16V.

Housed in a 14-SOIC (0.154" body width, 3.90 mm) with supplier device code 14-SO. Surface-mount only.

No conflict-mineral or REACH restriction flags on this line.

Frequently asked questions

Is TS556IDTTR RoHS compliant?

Yes, the TS556IDTTR is ROHS3 compliant per STMicroelectronics classification. No exemptions beyond the standard ROHS3 scope apply.

What supply voltage range does TS556IDTTR work with?

The TS556IDTTR operates from 2V to 16V. This covers 3.3V, 5V, 12V, and 15V rails commonly found in industrial and automotive systems. No minimum load is required for regulation — the timer functions across the full range.

What temperature range is TS556IDTTR rated for?

Industrial temperature grade: -40°C to 125°C. Suitable for outdoor telecom cabinets, motor drive compartments, and under-hood automotive auxiliary circuits that see elevated ambient temperatures.
