Product Description

The 74HCT257D@652 provides four independent 2-input multiplexers with common select and output enable inputs. The device features 3-state outputs that can be used in bus-oriented applications. The 3-state outputs are controlled by the output enable input, allowing the outputs to assume a high-impedance state. When the output enable input is high, the outputs are in a high-impedance state, regardless of the multiplexer inputs.

With a wide operating voltage range of 4.5V to 5.5V, the 74HCT257D@652 multiplexer operates within the industry-standard voltage range, ensuring compatibility with other TTL logic families. The device is housed in a slim SOIC 16-pin package, which is designed for optimized board space efficiency.

The propagation delay of 8ns at 4.5V is indicative of the device's high-speed performance. The 74HCT257D@652 operates over an extended temperature range from -40°C to +125°C, which ensures reliable operation even under extreme environmental conditions.
