? semiconductor components industries, llc, 2000 august, 2000 rev. 4 1 publication order number: mc14513b/d mc14513b bcd-to-seven segment latch/decoder/driver cmos msi (lowpower complementary mos) the mc14513b bcdtoseven 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 4bit storage latch, an 8421 bcdtoseven segment decoder, and has output drive capability. lamp test (lt ), blanking (bi ), and latch enable (le) inputs are used to test the display, to turnoff or pulse modulate the brightness of the display, and to store a bcd code, respectively. the ripple blanking input (rbi) and ripple blanking output (rbo) can be used to suppress either leading or trailing zeroes. it can be used with sevensegment 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. ? low logic circuit power dissipation ? highcurrent sourcing outputs (up to 25 ma) ? latch storage of binary input ? blanking input ? lamp test provision ? readout blanking on all illegal input combinations ? lamp intensity modulation capability ? time share (multiplexing) capability ? adds ripple blanking in, ripple blanking out to mc14511b ? supply voltage range = 3.0 v to 18 v ? capable of driving two lowpower ttl loads, one lowpower schottky ttl load to two htl loads over the rated temperature range. maximum ratings (voltages referenced to v ss ) (1.) symbol parameter value unit v dd dc supply voltage range 0.5 to +18.0 v v in input voltage range, all inputs 0.5 to v dd + 0.5 v i dc current drain per input pin 10 ma p d power dissipation, per package (2.) 500 mw t a operating temperature range 55 to +125 c t stg storage temperature range 65 to +150 c i ohmax maximum conti nuous output drive current (source) per output 25 ma p ohmax maximum continuous output power (source) per output (3.) 50 mw http://onsemi.com a = assembly location wl, l = wafer lot yy, y = year ww, w = work week device package shipping ordering information mc14513bcp pdip18 20/rail marking diagrams 1 18 pdip18 p suffix case 707 mc14513bcp awlyyww this device contains protection circuitry to protect the inputs against damage due to high static voltages or electric fields. however, it is advised that normal precautions be taken to avoid application of any volt- age higher than maximum rated voltages to this high impedance circuit. a destructive high current mode may occur if v in and v out are not constrained to the range v ss (v in or v out ) v dd . due to the sourcing capability of this circuit, dam- age can occur to the device if v dd is applied, and the outputs are shorted to v ss and are at a logical 1 (see maximum ratings). unused inputs must always be tied to an appropri- ate logic voltage level (e.g., either v ss or v dd ). 1. maximum ratings are those values beyond which damage to the device may occur. 2. temperature derating: plastic ap and d/dwo packages: 7.0 mw/ c from 65 c to 125 c 3. p ohmax = i oh (v dd v oh )
