16-bit Registered Transceivers with 3-state Outputs
ADE-205-169A (Z)
2nd. Edition
December 1999
The HD74ALVCH16543 can be used as two 8-bit transceivers or one 16-bit transceiver. Separate latch
enable (
LEAB or LEBA) and output enable (OEAB or OEBA) inputs are provided for each register to
permit independent control in either direction of data flow. The A to B enable (
CEAB) input must be low
in order to enter data from A or to output data from B. If
CEAB is low and LEAB is low, the A to B
latches are transparent; a subsequent low to high transition of
LEAB puts the A latches in the storage mode.
CEAB and OEAB both low, the 3-state B outputs are active and reflect the data present at the output
of the A latches. Data flow from B to A is similar but requires using
CEBA, LEBA, and OEBA. Active
bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
• V
CC = 2.3 V to 3.6 V
• Typical V
OL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
• Typical V
OH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)
• High output current ±24 mA (@V
CC = 3.0 V)
• Bus hold on data inputs eliminates the need for external pullup / pulldown resistors
