DESCRIPTION
The M74HC4511 is an high speed CMOS
BCD-TO-7 SEGMENT LATCH/DECODER/
DRIVER fabricated with silicon gate C2MOS
technology.
The segment output driver has large IOH capability
which enables common cathode leds to be directly
driven.
When lamp test (LT) is taken "L", all segment
outputs will go to "H", and when blanking (BI) is
taken "L" and LT is taken "H" all segment outputs
will go to "L".

These functions operate regardless of other inputs
and are used to test the display.
Input BI is used to pulse-modulate the brightness
of the display.
When an error input code (over 10) is applied to
the BCD input, all segment outputs will go "L" (turn
off).
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
