UTCMC14511 Datasheet CMOS Ic Bcd-to-seven Segment Latch/decoder/driver

Manufacturer: Unisonic Technologies

Overview: UTC MC14511 BCD-TO-SEVEN SEGMENT LATCH/DECODER/DRIVER.

General Description

The UTC MC14511 BCD–to–seven segment latch/decoder/driver is constructed with plementary 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.

Key Features
