Description

The N74F245N is a kind of octal transceiver featuring non-inverting 3-State bus compatible outputs in both transmit and receive directions. The B port outputs are capable of sinking 64mA and sourcing 15mA, producing very good capacitive drive characteristics. The N74F245N features an Output Enable (OE) input for easy cascading and Transmit/Receive (T/R) input for direction control. The 3-State outputs, B0B7, have been designed to prevent output bus loading if the power is removed from the device.

There are some features of N74F245N as follows: (1)Octal bidirectional bus interface; (2)3-State buffer outputs sink 64mA; (3)15mA source current; (4)Outputs are placed in high impedance state during power-off conditions.

Then is about the absolute maximum ratings of N74F245N: (1)VCC, Supply voltage: 0.5 to +7.0 V; (2)VIN, Input voltage: 0.5 to +7.0 V; (3)IIN, Input current: 30 to +5 mA; (4)VOUT, Voltage applied to output in high output state: 0.5 to +5.5 V; (5)IOUT, Current applied to output in low output state: A0-A7: 48 mA; B0-B7: 128 mA; (6)Tamb, Operating free air temperature range: 0 to +70; (7)Tstg, Storage temperature range: 65 to +150.
