产品概述
These TTL encoders feature priority decoding of the inputs to ensure that
only the highest-order data line is encoded. The 'LS348 circuits encode eight
data lines to three-line (4-2-1) binary (octal). Cascading circuitry (enable
input EI and enable output EO) has been provided to allow octal expansion.
Outputs A0, A1, and A2 are implemented in three-state logic for easy expansion
up to 64 lines without the need for external circuitry. See Typical Application
Data.
