A6821SAT

The A6821SAT is designed as one kind of DABiC-5 8-bit serial input latched sink drivers which formed by three parts:an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking darlington output drivers. It can be used in multiplexed LED displays and incandescent lamps. By using the serial data output, the drivers can be cascaded for interface applications requiring additional drive lines.

Features of the A6821SAT are:(1)3.3 V to 5 V logic supply range;(2)power on reset (POR);(3)to 10 MHz data input rate;(4)CMOS, TTL compatible;(5)-40°C operation available;(6)schmitt trigger inputs for improved noise immunity;(7)low-power CMOS logic and latches;(8)high-voltage current-sink outputs;(9)internal pull-up/pull down resistors.

The absolute maximum ratings of the A6821SAT can be summarized as:(1)output voltage:50 V;(2)logic supply voltage:7 V;(3)input voltage range:-0.3 V to VDD+0.3 V;(4)continuous output current (each output):500 mA;(5)package power dissipation:2.1 W;(6)operating temperature range (ambient temperature, TA):-20°C to +85°C;(7)operating temperature range (storage temperature, Ts):-55°C to +150°C.
