The ALVCH16245 is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements. This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. The ALVCH16245 has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. The ALVCH16245 has “bus-hold” which retains the inputs’ last state whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. • 3.3V high speed systems • 3.3V and lower voltage computing systems FUNCTIONAL BLOCK DIAGRAM 1DIR 1 2DIR 48 24 25 36 13 35 14 33 16 32 17 30 19 29 20 27 22 1OE 2A1 2OE 1A1 47 2 46 3 44 5 43 6 41 8 40 9 38 11 1B1 2A2 1B2 2A3 1B3 2A4 1B4 2A5 1B5 2A6 1B6 2A7 1B7 2A8 26 2B1 1A2 2B2 1A3 2B3 1A4 2B4 1A5 2B5 1A6 2B6 1A7 2B7 1A8 37 12 1B8 23 2B8 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
