Frequently Asked Questions
How many I/O pins does PIC16C74B-04/L provide and how are they distributed?
The PLCC-44 package gives the PIC16C74B-04/L 44 pins in total, with a substantial number dedicated to general-purpose I/O, enabling designs that need to interface with multiple sensors, actuators, and communication peripherals simultaneously in a socketed footprint.
What is the maximum operating frequency of PIC16C74B-04/L and how does that affect throughput?
The PIC16C74B-04/L runs at a maximum clock frequency of 4 MHz, executing single-cycle instructions at up to 1 MIPS, which is sufficient for low-speed control loops, serial communication handling, and ADC-based data acquisition in legacy embedded systems.
Is PIC16C74B-04/L still recommended for new designs given its introduction date of 1990?
With an introduction date of 1990 and a YTEOL rating of 3, this device is approaching end-of-life status and is not recommended for new designs. Engineers should consider migrating to newer 8-bit PIC16F or PIC16LF devices that offer higher clock speeds up to 32 MHz and smaller modern packages.
