CD4511BC BCD-to-7 Segment Latch/Decoder/Driver October 1987 Revised January 1999 CD4511BC BCD-to-7 Segment Latch/Decoder/Driver General Description 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. 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 s Low logic circuit power dissipation s High current sourcing outputs (up to 25 mA) s Latch storage of code s Blanking input s Lamp test provision s Readout blanking on all illegal input combinations s Lamp intensity modulation capability s Time share (multiplexing) facility s Equivalent to Motorola MC14511 Ordering Code: Order Number CD4511BCWM CD4511BCN Package Number M16B N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300” Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Devices also available in Tape and Reel.
