The IC component 74HCT251DB,118 is a 3-state 8-bit multiplexer with input latches, manufactured by NXP Semiconductors. It is a member of the 74HCT series, which is compatible with the standard 74LS logic families. This component offers various features that make it suitable for multiplexing applications.
Key features of the 74HCT251DB,118 include:
1. 3-state outputs: The component provides 8 outputs with a 3-state function, allowing the outputs to be enabled or disabled based on control signals.
2. Latched inputs: It has a latch enable (LE) input pin that enables latching of the input data prior to a selection being made, ensuring that the selected data remains stable.
3. 8 data inputs: The component offers 8 data input lines (D0-D7), which can be used to transmit signals from different sources into a single output line based on the selection signals.
4. Common Select input: A single Select (S) input pin selects one of the 8 data inputs to be transmitted to the output line.
5. Active LOW enable: The component features an active LOW enable input (E\), which allows for easy control over the operation of the multiplexer.
6. Wide operating voltage range: The 74HCT251DB,118 can operate within a wide voltage range of 4.5V to 5
