74HC4511; 74HCT4511
BCD to 7-segment latch/decoder/driver
Rev. 3 — 15 November 2016
Product data sheet
1. General description
The 74HC4511; 74HCT4511 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 LT
and 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.
