74AVC2T45
Dual-bit, dual-supply voltage level translator/transceiver; 3-state
The 74AVC2T45 is a dual-bit, dual-supply transceiver that enables bidirectional level translation. It features two data input-output ports (nA and nB), a direction control input (DIR) and dual?-?supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any voltage between 0.8 V and 3.6 V making the device suitable for translating between any of the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins nA and DIR are referenced to VCC(A) and pins nB are referenced to VCC(B). A HIGH on DIR allows transmission from nA to nB and a LOW on DIR allows transmission from nB to nA.
The device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In Suspend mode when either VCC(A) or VCC(B) are at GND level, both A and B are in the high-impedance OFF-state.
Features and benefits
Wide supply voltage range:
VCC(A): 0.8 V to 3.6 V
VCC(B): 0.8 V to 3.6 V
High noise immunity
Complies with JEDEC standards:
JESD8-12 (0.8 V to 1.3 V)
JESD8-11 (0.9 V to 1.65 V)
JESD8-7 (1.2 V to 1.95 V)
JESD8-5 (1.8 V to 2.7 V)
JESD8-B (2.7 V to 3.6 V)
Maximum data rates:
500 Mbit/s (1.8 V to 3.3 V translation)
320 Mbit/s (<1.8 V to 3.3 V translation)
320 Mbit/s (translate to 2.5 V or 1.8 V)
280 Mbit/s (translate to 1.5 V)
240 Mbit/s (translate to 1.2 V)
Suspend mode
Latch-up performance exceeds 100 mA per JESD 78 Class II
Inputs accept voltages up to 3.6 V
Low noise overshoot and undershoot < 10 % of VCC
IOFF circuitry provides partial Power-down mode operation
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 3B exceeds 8000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and -40 °C to +125 °C
