MPN:PIC16F877A

PIC16F877A Microcontroller IC from Microchip – High-performance 8-bit MCU ideal for embedded systems, automation, and electronic projects. Made in the USA.

MPN:SN74HC540N
The SN74HC540N is an octal inverting buffer and line driver IC from Texas Instruments, part of the 74HC (High-Speed CMOS) logic family. It features 3-state outputs controlled by two active-low enable pins, allowing it to drive data buses efficiently. With low power consumption, high noise immunity, and fast switching speeds, the SN74HC540N is ideal for bus buffering, signal inversion, memory addressing, and data line driving. The N suffix denotes a DIP through-hole package, suitable for prototyping and industrial applications.

MPN:SN74HC74N
The SN74HC74N is a dual positive-edge-triggered D-type flip-flop from Texas Instruments, belonging to the 74HC (High-Speed CMOS) logic family. Each flip-flop includes independent asynchronous preset (SET) and clear (RESET) inputs, allowing direct control of the output state. The device operates with low power consumption and high noise immunity, making it ideal for data storage, frequency division, registers, counters, and digital control circuits. The N suffix indicates a DIP through-hole package.
