HD74ALVCH16245 6-bit Bus Transceivers with 3-state Outputs REJ03D0049-0500Z (Previous ADE-205-134C(Z)) Rev.5.00 Oct.02.2003 Description The HD74ALVCH16245 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 allow 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 output enable (OE) input can be used to disable the device so that the buses are effectively isolated. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Features VCC = 2.3 V to 3.6 V Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) Bus hold on data inputs eliminates the need for external pullup / pulldown resistors Function Table ...
