Overview
The NCV1455BDR2 is a monolithic timing circuit from onsemi, part of the MC1455 family. It operates within a supply voltage range of 4.5 V to 16 V and supports both astable and monostable modes. The device features a high-current output capable of sourcing or sinking up to 200 mA, allowing direct drive of TTL loads. Timing accuracy is maintained with a temperature stability of 0.005% per °C. The NCV prefix indicates suitability for automotive applications requiring specific site and change control standards. It is housed in an SOIC-8 package.
Feature Summary
- Direct replacement for NE555 timers with adjustable duty cycle
- High current output structure sources or sinks 200 mA
- Timing range spans microseconds through hours
- Temperature stability of 0.005% per °C
Applications
- Time delay generation
- Pulse width modulation
- Missing pulse detection
- Sequential timing sequences
Procurement Notes
Verify the NCV prefix confirms automotive-grade site and change control requirements. Confirm the DR2 suffix corresponds to the SOIC-8 tape and reel packaging format containing 2500 units. Ensure the operating temperature range of -40°C to +125°C aligns with the target application environment specifications.
Selection Notes
Select this component when a direct NE555 replacement is needed with extended industrial or automotive temperature ratings. The NCV1455BDR2 provides a wider operating range (-40°C to +125°C) compared to standard commercial variants. Use when high output current (200 mA) is required to drive loads directly without additional buffering stages.
Part Context
This part belongs to the MC1455/NCV1455B timer family manufactured by onsemi. It shares functional compatibility with the MC1455 and MC1455B series but carries the NCV designation for automotive qualification. The D suffix denotes the SOIC-8 narrow body package, while DR2 indicates tape and reel shipping.
