Frequently Asked Questions
What makes the HCC40193BDG suitable for space applications, and what supply voltage range does it support?
The HCC40193BDG is radiation-hardened to withstand total ionizing dose levels encountered in satellite orbits, and it operates across a wide supply range of 3 V to 15 V. The ceramic DIP-16 hermetic package resists moisture and outgassing, meeting the stringent requirements of space and avionics qualification programs such as MIL-PRF-38535.
How does the presettable parallel load feature of the HCC40193BDG work, and in what scenarios is it useful?
When the LOAD input is asserted low, the 4-bit counter asynchronously loads the value present on its four parallel data inputs (D0–D3) within one propagation delay, regardless of the clock. This lets firmware preset the counter to a specific start count — for instance, loading a value of 6 to count modulo-10 cycles — without resetting the entire counter chain to zero first.
Can the HCC40193BDG be cascaded to build wider counters, and how are the carry and borrow outputs used?
Yes, the device provides separate CARRY (active-low) and BORROW (active-low) outputs that pulse when the counter overflows through 15 (carry) or underflows through 0 (borrow). By connecting the CARRY output of a lower stage to the UP clock of the next stage, and BORROW to the DOWN clock, designers can chain 4-bit stages to build 8-bit, 12-bit, or larger counters, supporting up to 16 distinct count states per stage.
