Quadruple Bus Transceiver
DM74LS243 Quadruple Bus Transceiver August 1986 Revised January 2000 DM74LS243 Quadruple Bus Transceiver General Description Features This four data line transceiver is designed for asynchro- � Two-way asynchronous communication between data nous two-way communications between data buses. It can buses be used to drive terminated lines down to 133Ω. � PNP inputs reduce DC loading on bus line � Hysteresis at data inputs improves noise margin Ordering Code: Order Number Package Number Package Description DM74LS243M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 Narrow DM74LS243N N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
