Overview
MOTOROLA SEMICONDUCTOR TECHNICAL DATA BCD-to-Seven-Segment Latch/ Decoder/Display Driver High–Performance Silicon–Gate CMOS The MC74HC4511 is identical in pinout to the MC14511 metal–gate CMOS decoder/driver.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC4511 provides the functions of a 4–bit storage latch, a BCD–to– seven–segment decoder, and a display driver.
It can be used either directly or indirectly with seven–segment light–emitting diode (LED), incandescent, fluorescent, gas discharge, or liquid–crystal readouts.
Lamp test (LT), blanking (BI), and latch enable (LE) inputs are used to test the display, to turn off or pulse modulate the brightness of the display, and to store a BCD code, respectively.
