FEATURES
GENERAL DESCRIPTION
The 74HC/HCT4511 are high-speed Si-gate CMOS
devices and are pin compatible with “4511” of the “4000B”
series. They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT4511 are BCD to 7-segment
latch/decoder/drivers with four address inputs (D
an active LOW latch enable input (LE), an active LOW

When LE goes HIGH, the last data present on D
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.
