74AVC4TD245
4-bit dual supply translating transceiver; 3-state
7. Functional description
[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
[2] The An, DIRn and OE
input circuit is referenced to V
CC(A)
; The Bn input circuit is referenced to V
CC(B)
.
[3] If at least one of V
CC(A)
or V
CC(B)
is at GND level, the device goes into suspend mode.
