UPD16334 Description
Symbol PC BLK LE OE A1 to A3 (6) Pin Name Polarity change input Blank input Latch enable input Output enable RIGHT data input/output LEFT data input/output (Note) Description PC = L: All driver output invert BLK = H : All output = H or L Automatically executes latch by setting high at rising edge of the clock Make output high impedance by input H When R/L=H (values in parentheses are for 6-bit input) A1 to A3 (6).
