Frequently Asked Questions
What is the counting direction of the CD74HC163MG4?
The CD74HC163MG4 is an up-counter, meaning it counts in the binary ascending direction from 0 to 15 and then overflows back to 0. It does not count downward; for bidirectional counting applications, an up-down counter variant such as the 74HC193 would be more appropriate.
Does the CD74HC163MG4 have a synchronous or asynchronous clear?
The CD74HC163MG4 features a synchronous clear input, meaning the counter resets to zero on the next rising clock edge when the clear signal is asserted, rather than immediately asynchronously. This synchronous behavior prevents glitches in the count outputs and ensures clean transitions in high-speed clocked digital circuits.
What is the purpose of the TCO (terminal count output) on the CD74HC163MG4?
The terminal count output (TCO) goes high when the counter reaches its maximum count value of 15 (binary 1111) and both count enable inputs are active. This signal is used for cascading multiple CD74HC163MG4 devices to create wider counters, or for triggering downstream logic when the counter completes a full counting cycle.
What supply voltage range does the CD74HC163MG4 support?
As an HC-family CMOS logic device, the CD74HC163MG4 operates over a supply voltage range of approximately 2V to 6V. This wide voltage range makes it compatible with both 3.3V and 5V digital logic systems, and it can be used in battery-powered portable applications as well as standard 5V TTL-compatible digital circuits.
What package is the CD74HC163MG4 available in?
The CD74HC163MG4 is available in a 16-pin SOIC package (JESD-30 code R-PDSO-G16), which is a standard surface-mount package compatible with automated PCB assembly. The G4 suffix indicates RoHS-compliant and Green manufacturing, confirmed by JESD-609 code e4, making it suitable for environmentally regulated markets worldwide.
