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 = 3.0V ~ 18V
