ACTIVE. SOIC. DW. 20. 2000. Green (RoHS. & no Sb/Br). CU NIPDAU | CU SN. Level-1-260C-UNLIM. buffer used is a SN74LVC244ADWR buffer (DigiKey PN 296-1229-1-ND). This signal is also used to drive the direction pin on the Data Bus buffer. WRn/R_W. The PCF8584 Pin 18 signal is a buffered version of the eZ80F91. MCUs Pin 52 WRn signal. This signal is labelled CTRL3 in the schematic and the buffer used is a SSOP. 20. 74LVQ244MSAX. Fairchild Semiconductor. Discontinued. SN74LVC244ADBR. Q. SSOP. 20. 74LVQ244MTR.
