Description

The 74HC48N IC is a BCD to 7-segment latch/decoder/driver with four address inputs (A, B, C, D), a latch enables input (LE), a ripple blanking input (BI), a lamp test input (LT), and seven-segment outputs (a to g).

When LE is LOW, the segment outputs (a to g) follow the A to D data.

When LE goes HIGH, the data on A to D is latched, and the segment outputs stay constant.

With LT LOW, all segment outputs go HIGH, regardless of other inputs.

When LT is HIGH and BI is LOW, all segment outputs go LOW.

LT and BI inputs don't affect the latch circuit and include clamp diodes. This allows for the use of current-limiting resistors when interfacing inputs with voltages above VCC.
