NXP Semiconductors ICM7555CD

The ICM7555 is a CMOS timer providing signiﬁcantly improved performance over the standard NE/SE555 timer, while at the same time being a direct replacement for those devices in most applications. The ICM7555 is a stable controller capable of producing accurate time delays or frequencies. For astable operation as an oscillator, the free-running frequency and the duty cycle are both accurately controlled by two external resistors and one capacitor.
