ST Micro M74HC00B1 Quad 2 Input NAND Gate DIL14

Manufactured by STMicrolectronics:  Part # M74HC00B1 (74HC00):  DIL14 Through Hole Package

74 Series CMOS

The 74HC00 is a quad 2-input NAND gate. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
