The 74HC/HCT240 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL

(LSTTL). They are specified in compliance with JEDEC standard no. 7A.

The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, D²PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents. 

he LM317T is a versatile, adjustable positive linear voltage regulator IC that can supply over 1.51.51.5 amps with an output voltage range of 1.21.21.2 to 373737 volts. It is easy to use, requiring only two external resistors to set the output voltage and featuring internal protections like current limiting and thermal shutdown. Common applications include creating adjustable power supplies, programmable regulators, and current regulators.
