DM74ALS5245/74ALS5245-1 Octal TRI-STATE Transceiver March 1998 DM74ALS5245/74ALS5245-1 Octal 3-STATE Transceiver General Description This octal bus transceiver is designed for asynchronous two-way communication between data buses. The inputs include hysteresis which provides improved noise rejection. Data is transmitted either from the A bus to the B bus or from the B bus to the A bus depending on the logic level of the direction control (DIR) input. The device can be disabled via the enable input (G ) which causes the outputs to enter the high impedance mode so the buses are effectively isolated. The ALS5245-1 features the same performance as the ALS5245 with the addition of increased current drive capability to meet the requirements of various bus architectures. The recommended maximum IOL is increased to 48 mA. Features n Input Hysteresis n Low output noise generation n High input noise immunity n Advanced oxide-isolated, ion implanted Schottky TTL process n Switching specification guaranteed over the full temperature and VCC range n PNP inputs to reduce input loading n Maximum IOL is increased to 48 mA for ALS5245-1 Ordering Code: Order Number Package Number DM74ALS5245WM M20B DM74ALS5245SJ M20D DM74ALS5245N N20A DM74ALS5245-1WM M20B DM74ALS5245-1SJ M20D DM74ALS5245-1N N20A Package Description 20-Lead Small Outline Package – JEDEC (M) 20-Lead Small Outline Package – EIAJ (SJ) 20-Lead Molded Dual-in-Line Package (N) 20-Lead Small Outline Package – JEDEC ...
