UTC MC14511

CMOS IC

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),

SOP-16

DIP-16

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 = 3.0 V ~ 18 V

* Capable of Driving Two Low-power TTL Loads, One

Low-power Schottky TTL Load or Two HTL Loads Over

the Rated Temperature Range

* Chip Complexity: 216 FETs or 54 Equivalent Gates

* Triple Diode Protection on all Inputs
