SN74LV245APWLE

The SN74LV245APWLE is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR) input. The features of the SN74LV245APWLE are: (1)2V to 5.5V VCC operation; (2)max tpd of 6.5ns at 5V; (3)typical VOLP<0.8V at VCC=3.3V, TA=25; (4)typical VOHV<0.8V at VCC=3.3V, TA=25; (5)support mixed-mode voltage operation on all ports; (6)Ioff supports partial-power-down mode operation; (7)latch-up performance exceeds 250mA per JESD 17.

The following is about the absolute maximum ratings of SN74LV245APWLE: (1)Supply voltage range, VCC: 0.5 V to 7 V; (2)Input voltage range, VI: Except I/O ports: 0.5 V to VCC + 0.5 V, I/O ports: 0.5 V to VCC + 0.5 V; (3)Output voltage range, VO: 0.5 V to VCC + 0.5 V; (4)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA; (5)Output clamp current, IOK (VO < 0 or VO > VCC): ±50 mA; (6)Continuous output current, IO (VO = 0 to VCC): ±35 mA; (7)Continuous current through VCC or GND: ±70 mA; (8)Maximum power dissipation at TA = 55°C (in still air): DB package 0.6 W, DW package 1.6 W, PW package 0.7 W; (9)Storage temperature range, Tstg: 65°C to 150°C.

The electrical characteristics of the SN74LV245APWLE are: (1)VOH: VCC-0.1V min at IOH=-50A, VCC=2V to 5.5V; (2)VOL: 0.1V max at IOL=50A, VCC=2V to 5.5V; (3)II: ±1A max at VI=5.5V or GND, VCC=0 to 5.5V; (4)IOZ: ±5A max at VO=VCC or GND, VCC=5.5V; (5)ICC: 20A max at VI=VCC or GND, IO=0, VCC=5.5V; (6)Ci: 3pF max at VCC=5V.
