NE555P Single Precision Timer IC
These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or mono-stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a-stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.

PALCE16V8H-10PC
The PALCE16V8 is executed in a 20-pin 300-mil molded DIP, a 300-mil cerdip, a 20-lead square ceramic leadless chip carrier, and a 20-lead square plastic leaded chip carrier. The device provides up to 16 inputs and 8 outputs. The PALCE16V8 can be electrically erased and reprogrammed. The programmable macrocell enables the device to function as a superset to the familiar 20-pin PLDs such as 16L8, 16R8, 16R6, and 16R4. The PALCE16V8 features 8 product terms per output and 32 input terms into the AND array. The first product term in a macrocell can be used either as an internal output enable control or as a data product term.

DATASHEET
PCF8574AT
The PCF8574/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)). The devices consist of eight quasi-bidirectional ports, 100 kHz I2C-bus interface, three hardware address inputs and interrupt output operating between 2.5 V and 6 V
