FEATURES - Wide Operating Voltage Range of 2.0V to 6.0V - Outputs Can Drive up to 10 LSTTL Loads - Low Power Consumption, 20µA Maximum ICC - Typical tpd = 8ns - ±4mA Output Drive at 5.0V - Low Input Current of 1µA Maximum   DESCRIPTION The 74HC00 contain four independent, 2-input NAND gates. They perform the Boolean function Y = A̅ × B̅, or Y = A̅ + B̅ in positive logic. Inputs include clamp diodes.   read more

FEATURES - Wide Supply-Voltage Range: 4.5V to 36V - Separate Input-Logic Supply - Internal ESD Protection (HBM 2kV) - High-Noise-Immunity Inputs - Output Current 600mA Per Channel - Peak Output Current 1.2A Per Channel - Output Clamp Diodes for Inductive Transient Suppression   DESCRIPTION The L293D device is quadruple high-current half-H drivers. The L293D is designed to provide bidirectional drive currents of up to 600mA at voltages from 4.5V to 36V. Both devices ae designed to driver inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications. Each output is a complete totem-pole drive circuit, with a Darlington transistor sink and a pseudo-Darlington source. Drivers are enabled in pairs, with drivers 1 and 2 enabled by EN1/2 and drivers 3 and 4 enabled by EN3/4. The L293D is characterized for operation from 0°C to 70°C.   read more
