The 74LVT245B is an 8-bit transceiver with 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
Wide supply voltage range from 2.7 V to 3.6 V
3-state buffers
Octal bidirectional bus interface
Overvoltage tolerant inputs to 5.5 V
Direct interface with TTL levels
BiCMOS high speed and output drive
Output capability: +64 mA/-32 mA
Latch-up protection exceeds 500 mA per JEDEC Std 17
Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs
No bus current loading when output is tied to 5 V bus
Live insertion/extraction permitted
Power-up 3-state
IOFF circuitry provides partial Power-down mode operation
Complies with JEDEC standard 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
Specified from -40 °C to 85 °C
