MM74HC148

`Typical propagation delay: 13 ns
`Wide supply voltage range: 2V6V

The MM74HC148 priority encoder utilizes advanced silicon- gate CMOS technology. It has the high noise immunity and low power consumption typical of CMOS circuits, as well as the speeds and output drive similar to LB-TTL.

This priority encoder MM74HC148 accepts 8 input request lines 07 and outputs 3 lines A0A2. The priority encoding ensures that only the highest order data line is encoded. Cascading circuitry (enable input EI and enable output EO) has been provided to allow octal expansion without the need for external circuitry. All data inputs and outputs of MM74HC148 are active at the low logic level.

All inputs of MM74HC148 are protected from damage due to static discharge by internal diode clamps to V_CC and ground.
