The SN74HC14DR from Texas Instruments is a versatile integrated circuit containing six independent inverters, each featuring Schmitt-trigger inputs. This design allows for reliable signal conditioning and noise immunity.
This device operates over a wide voltage range of 2V to 6V and a temperature range of -40°C to +85°C, making it suitable for diverse environmental conditions. It supports fanout up to 10 LSTTL loads and offers significant power reduction compared to LSTTL logic ICs.
The SN74HC14DR is available in a 14-SOIC surface-mount package, facilitating integration into compact electronic designs. Each inverter gate performs the Boolean function Y = A in positive logic, making it useful for synchronizing clock inputs, debouncing switches, or inverting digital signals.
Key electrical characteristics include a maximum propagation delay of 21ns at 6V and 50pF, a maximum supply current of 20µA, and output drive capabilities of IOL (max) at 4mA and IOH (max) at -4mA. The input logic levels range from 1.5V to 4.2V.
