555 Timer, Intersil. Intersil offers the 555 timer, a highly stable controller capable of producing accurate timing pulses. With monostable operation, you control the time delay by one external resistor and one capacitor. With a stable operation, the frequency and duty cycle are accurately controlled with two external resistors and one capacitor. Timing From Microseconds to Days ICM7242 is a Long Range Fixed Timer More information:  | | Mounting Type: | Surface Mount | Timer Type: | Standard | Package Type: | SOIC | Number of Internal Timers: | 1 | Pin Count: | 8 | Maximum Input Frequency: | 1MHz | Minimum Operating Supply Voltage: | 2 V | Maximum Operating Supply Voltage: | 18 V | Minimum Operating Temperature: | -25 °C | Maximum Operating Temperature: | +85 °C | Maximum Low Level Output Current: | 20mA | Maximum High Level Output Current: | -0.8mA | Dimensions: | 5 x 4 x 1.5mm | Height: | 1.5mm | Length: | 5mm |
