HD74ALVCH162270 - 12-bit to 24-bit Registered Bus Exchanger with 3-state Outputs

Hitachi Semiconductor

Datasheet Details

The HD74ALVCH162270 is used in applications where data must be transferred from a narrow high speed bus to a wide lower frequency bus..

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).
High output current ±12 mA (@VCC = 3.0 V).
Bus hold on data inputs eliminates the need for external pullup / pulldown resistors.
All outputs have equivalent 26 Ω series resistors, so no external resistors are required. HD74ALVCH162270 Function Table Inputs CLK ↑ ↑ ↑ ↑ OEA H H L L OEB H L H L Outputs A.
