MC14511B_14 Datasheet, PDF (1/10 Pages) ON Semiconductor – BCD-to-Seven Segment Latch/Decoder/Drive

MC14511B
BCD-to-Seven Segment
Latch/Decoder/Driver
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.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Maximum Ratings are those values beyond which damage to the device may occur.
2. Temperature Derating: “D/DW” Packages: –7.0 mW/°C From 65°C to 125°C
3. P_OHmax = I_OH (V_DD − V_OH)
