SCES530H December 2003 – December 2014 SN74AVC1T45
The SN74AVC1T45 is single-bit, dual-supply, noninverting voltage level translation. Pin A and direction control pin are support by VCCA and pin B is support by VCCB. The A port is able to accept I/O voltages ranging from 1.2 V to 3.6 V, while the B port can accept I/O voltages from 1.2 to 3.6 V. The high on DIR allows data transmission from A to B and a low on DIR allows data transmission from B to A.
Both VCCA and VCCB can be supplied at any voltage between 1.2 V and 3.6 V making the device suitable for translating between any of the voltage nodes (1.2-V, 1.8-V, 2.5-V and 3.3-V).
SN74AVC1T45 can support high data-rate application. The translated signal data rate can be up to 500 Mbps when signal is translated from 1.8 V to 3.3 V.
Ioff will prevent backflow current by disabling I/O output circuits when device is in partial-power-down mode.
