Inverter Gates Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to confirm pinout and electrical specifications. Ensure the selected component matches the required logic family (HC) and package type (SOIC-14). Cross-reference datasheets for exact timing parameters under your specific load conditions. Confirm RoHS compliance status if required by your manufacturing standards.

Inverter Gates Selection Notes

Select this component when designing circuits requiring multiple 3-input NAND operations in a compact form factor. The HC series offers balanced speed and power consumption suitable for general digital applications. Consider the 2 V to 6 V supply range for flexibility in various voltage domains. Verify that the 25 ns propagation delay meets the timing requirements of your target application frequency.

Inverter Gates Part Context

This component is part of the Texas Instruments SN74HCxx series of high-speed CMOS logic devices. The HC series is widely used in consumer electronics and industrial controls due to its wide voltage range and compatibility with TTL inputs. The SN74HC804 specifically provides hex 3-input NAND functionality, distinguishing it from other logic families like inverters or flip-flops found in the same product line.

Inverter Gates Replacement Considerations

Compatible substitutes include other hex 3-input NAND gates from the HC series such as the SN74HC20 or SN74HC30, depending on input count requirements. Ensure any replacement maintains the SOIC-14 package and similar electrical characteristics. Verify pin-to-pin compatibility before substitution.
