UPC1555G2-E1-A

Overview

The UPC1555G2-E1-A is a timer circuit manufactured by Renesas Electronics, housed in an 8-pin plastic SOP (225 mil) package. It functions as a versatile timing signal generator capable of monostable and astable multivibrator configurations with minimal external components. The device features trigger, threshold, control, and reset pins for flexible operation. Key electrical characteristics include a supply voltage range of 4.5 V to 16 V, an output current capacity of up to 200 mA, and temperature stability of 0.005%/°C. Circuit current is specified at 3 mA with a 5 V supply.

Feature Summary

• High output current capacity of 200 mA allows direct driving of relays and lamps
• Supports both monostable and astable oscillation modes
• Compatible with TTL-level signals for direct interfacing
• Fast rising and falling times of 100 ns

Applications

• Monostable multivibrator circuits
• Astable oscillator applications
• Timing signal generation
• Relay driver circuits
• Lamp driver circuits

Part Context

This component belongs to the µPC1555 series of bipolar analog integrated circuits produced by Renesas Electronics. The 'G2' suffix indicates the specific SOP-8 package variant, while 'E1-A' denotes environmental compliance and packaging details. It serves as a general-purpose timer IC similar in function to standard 555 timers but optimized for surface-mount integration within Renesas's linear IC portfolio.

Replacement Considerations

When replacing this component, verify that the substitute supports the required 200 mA output current and operates within the 4.5 V to 16 V supply range. Ensure the replacement package matches the 8-pin SOP (225 mil) footprint. Standard 555 timer equivalents may require verification of pin compatibility and thermal performance under load.
