74HC20 - MC74HC20N Dual 4-Input NAND Gates

74S20 - DM74S20N Dual 4-Input NAND Gates

The GM76C28A is 2,048 wordsx8 bits asynchronous, static random access memory on a monolithic CMOS chip. Its very low standby power requirement makes it ideal for applications requiring non-volatile storage with back-up batteries.

CMOS Quad True/Complement Buffer, Line Driver, CMOS-to-TTL Driver

High-Speed CMOS Logic Triple 3-input NAND Gates.
The 74HC10 logic gates utilize silicon gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits. All devices have the ability to drive 10 LSTTL loads. The HC logic family is functionally pin compatible with the standard LS logic family.
