Q & A
- What is the package type of the 74HC259PW112?
The 74HC259PW112 comes in a 16-TSSOP package with a width of 0.173" (4.40mm). - What is the operating voltage range of the 74HC259PW112?
The operating voltage range is from 2 V to 6 V. - What is the propagation delay time of the 74HC259PW112?
The propagation delay time (DATA – Q) is typically between 15 to 36 ns at VCC = 6 V. - Does the 74HC259PW112 have ESD protection?
Yes, it has ESD protection with CDM: 1 kV, HBM: 1.5 kV, MM: 200 V. - What are the key features of the 74HC259PW112?
Key features include high speed, low power dissipation, high noise immunity, and symmetrical output impedance. - What are the typical applications of the 74HC259PW112?
It is used in memory and data storage systems, digital signal processing, automotive and industrial control systems, and embedded systems. - How many latch outputs does the 74HC259PW112 have?
The device has eight latch outputs (Q0-Q7). - What is the function of the ENABLE input in the 74HC259PW112?
