Additional Details:
The TC74HC158AP operates with a supply voltage (VCC) ranging from 2V to 6V. The typical propagation delay time is around 10ns at VCC = 5V. The device is available in a DIP (Dual In-Line Package) package. The input impedance is high, minimizing the load on the driving circuits. The operating temperature range is typically -40°C to +85°C. Each of the four multiplexers selects one of two inputs based on the select input. The selected input is then routed to the corresponding output. The enable input, when high, disables all outputs, forcing them to a low state. This feature is useful for bus isolation and wired-OR applications. The TC74HC158AP is pin-compatible with the 74LS158 and 74HC158 devices, allowing for easy upgrades in existing designs. When designing with this device, it's crucial to provide adequate decoupling capacitors near the power supply pins to minimize noise and ensure stable operation. Adhering to the manufacturer's recommended operating conditions ensures optimal performance and reliability.
