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 d.
• 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
