Overview
The CD74HC4059M96 is a high-speed CMOS logic CMOS programmable divide-by-N counter produced by Texas Instruments. This device is part of the CD74HC series and is pin-compatible with the CD4059A devices of the CD4000B series. It is designed to divide an input frequency by any number 'N' from 3 to 15,999, making it highly versatile for various frequency division and counting applications. The CD74HC4059M96 operates in a wide temperature range of -55°C to 125°C and is packaged in a 24-pin SOIC (DW) package.

Q & A
- What is the operating temperature range of the CD74HC4059M96? The operating temperature range is -55°C to 125°C.
- What is the supply voltage range for this device? The supply voltage range is 2V to 6V.
- What is the maximum count value for the CD74HC4059M96? The maximum count value can be up to 15,999 depending on the mode selected.
- What types of outputs does the CD74HC4059M96 support? It supports standard outputs up to 10 LSTTL loads and bus driver outputs up to 15 LSTTL loads.
- How does the Master Preset Initialization work? The Master Preset Initialization sets the counter to the preset state according to the jam inputs and keeps it in that state as long as the control inputs are low.
- What is the significance of the Mode-Select Inputs? The Mode-Select Inputs determine the modulus (divide-by number) of the first and last counting sections.
- What is the maximum junction temperature for this device? The maximum junction temperature is 150°C for plastic packages.
- How does the Latch Enable input function? A 'high' on the Latch Enable input causes the counter output to remain high until the latch input returns to 'low'.
- What are some common applications of the CD74HC4059M96? Common applications include communications digital frequency synthesizers, fixed or programmable frequency division, and 'time out' timers for consumer and industrial controls.
- What is the package type for the CD74HC4059M96? The package type is SOIC (DW) with 24 pins.
