Philips 74LV251
The 74LV251 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT251. The 74LV251 is an 8-input multiplexer with 8 binary inputs (I0 to I7), an output enable input (OE) and three select inputs (S0, S1, S2). Both outputs are in the high impedance OFF-state (Z) when the output enable input is HIGH, allowing multiplexer expansion by tying the outputs.| Part No. | 74LV251 |
