com BCD-to-Seven Segment Latch/Decoder/Driver MC14511B The MC14511B 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.
0 V to 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 • NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable • These Devices are Pb−Free and are RoHS Compliant SOIC−16 D SUFFIX CASE 751B SO−16 WB DW SUFFIX CASE 751G MARKING DIAGRAMS 16 16 14511BG AWLYWW 1 SOIC−16 14511B AWLYYWWG 1 SO−16 WB A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week G = Pb−Free Package ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions sect...
