74LS245 Product details

Description

These octal bus transceivers are designed for asynchronous two-way communication between data buses The control function implementation minimizes external timing requirements The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the direction control (DIR) input The enable input (G) can be used to disable the device so that the buses are effectively isolated Y Y Y Y Y Y

Features

Y Y Y Bi-Directional bus transceiver in a high-density 20-pin package TRI-STATE outputs drive bus lines directly PNP inputs reduce DC loading on bus lines Hysteresis at bus inputs improve noise margins Typical propagation delay times port-to-port 8 ns Typical enable disable times 17 ns IOL (sink current) 54LS 12 mA 74LS 24 mA IOH (source current) b 12 mA 54LS b 15 mA 74LS Alternate Military Aerospace device (54LS245) is available Contact a National Semiconductor Sales Office Distributor for s.
