BCD-TO-SEVEN SEGMENT

LATCH/DECODER/DRIVER



DESCRIPTION

The UTC MC14511 BCD–to–seven segment latch/decoder/driver

is constructed with complementary MOS (CMOS) enhancement mode

devices and NPN bipolar output drivers 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.
