74LVT2245; 74LVTH2245
3.3 V octal transceiver with 30 Ohm termination resistors; 3-state
The 74LVT2245; 74LVTH2245 is an 8?-?bit transceiver with 30 ? termination resistors and 3?-?state outputs. The device features an output enable (OE) and send?/?receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high?-?impedance OFF?-?state. Bus hold data inputs eliminate the need for external pull?-?up resistors to define unused inputs
Features and benefits
30 Ω output termination resistors
Octal bidirectional bus interface
3-state buffers
Wide supply voltage range from 2.7 V to 3.6 V
BiCMOS high speed and output drive
Output capability: +12 mA and -12 mA
TTL input and output switching levels
Overvoltage tolerant inputs to 5.5 V
Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
Live insertion and extraction permitted
Direct interface with TTL levels
Power-up 3-state
No bus current loading when output is tied to 5 V bus
IOFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 500 mA per JESD 78 Class II Level B
Complies with JEDEC standards JESD8C (2.7 V to 3.6 V)
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
