Overview
UNISONIC TECHNOLOGIES CO.
, LTD MC14511 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.
 FEATURES * Low Logic Circuit Power Dissipation * High–Current Sourcing Outputs (Up to 25 mA) * Latch Storage of Code * Blanking Input * Lamp Test Provision * Readout Blanking on all Illegal Input Combinations * Lamp Intensity Modulation Capability * Time Share (Multiplexing) Facility * Supply Voltage Range = 3.
