74AVC20T245
20-bit dual supply translating transceiver; 3-state
5.2 Pin description
[1] All GND pins must be connected to ground (0 V).
6. Functional description
[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
[2] If at least one of V
CC(A)
or V
CC(B)
is at GND level, the device goes into suspend mode.
[3] The nAn, nDIR and nOE
input circuit is referenced to V
CC(A)
; The nBn input circuit is referenced to V
CC(B)
.
