Revised January 2004 CD4511BC BCD-to-7 Segment Latch/Decoder/Driver General Description Features The CD4511BC 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. 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 Equivalent to Motorola MC14511 Applications include instrument (e.g., counter, DVM, etc.) display driver, computer/calculator display driver, cockpit display driver, and various clock, watch, and timer uses.
