74HC48 ( BCD to 7-Segment Decoder)

Regular price LE 20.00

Introduction :

 74HC48 BCD to 7-segment decoder/driver IC For Common Cathode (CC) configuration of seven segment.

  74HC48 is a BCD to 7-segment latch/decoder/driver with four address inputs (A, B, C, D), a latch enable input (LE), a ripple blanking input (BI), a lamp test input (LT), and seven segment outputs (a to g).

When LE is LOW, the state of the segment outputs (a to g) is determined by the data on A to D. When LE goes HIGH, the last data present on A to D are stored in the latches and the segment outputs remain stable.

When LT is LOW, all the segment outputs are HIGH independent of all other input conditions. With LT HIGH, a LOW on BI forces all segment outputs LOW.

The inputs LTand BI do not affect the latch circuit. Inputs include clamp diodes.

This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC
