Designed to be used in time delay relays for HVAC equipment and industrial controls, the LS7213 is a CMOS silicon gate delay timer IC that incorporates four operating modes and eight time delay ranges. The time delay ranges are configured to produce real-time delays when the input time-base frequency is kept within 10 kHz to 1 kHz. Features include an ac oscillator port for time-base generation and complementary delay outputs with an option to "flash" one output as a delay-in progress indicator. Delays are initiated by a trigger and can be aborted by a reset. The LS7213 is a 14-pin DIP and LS7213-S is packaged as a 14-pin SOIC. Pricing is $0.58 each/10,000.
