CD4511BC
BCD-to-7 Segment Latch/Decoder/Driver
General Description
The CD4511BC BCD-to-seven segment latch/decoder/
driver is constructed with complementary MOS (CMOS)
enhancement mode devices and NPN bipolar output driv-
ers in a single monolithic structure. The circuit provides the
functions of a 4-bit storage latch, an 8421 BCD-to-seven
segment decoder, and an output drive capability. 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. It can
be used with seven-segment light emitting diodes (LED),
incandescent, fluorescent, gas discharge, or liquid crystal
readouts either directly or indirectly.
Applications include instrument (e.g., counter, DVM, etc.)
display driver, computer/calculator display driver, cockpit
display driver, and various clock, watch, and timer uses.
Features
s Low logic circuit power dissipation
s High current sourcing outputs (up to 25 mA)
s Latch storage of code
s Blanking input
s Lamp test provision
s Readout blanking on all illegal input combinations
s Lamp intensity modulation capability
s Time share (multiplexing) facility
s Equivalent to Motorola MC14511
