Product Summary
The SN74HCT245DW is an octal bus transceiver. The SN74HCT245DW is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The SN74HCT245DW allows data transmission 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.
Parametrics
SN74HCT245DW absolute maximum ratings: (1)Supply voltage range, VCC:-0.5 V to 7 V; (2)Input clamp current, IIK (VI＜0 or VI＞VCC): ±20 mA; (3)Output clamp current, IOK (VO＜0 or VO＞ VCC): ±20 mA; (4)Continuous output current, IO (VO = 0 to VCC): ±35 mA; (5)Continuous current through VCC or GND: ±70 mA; (6)Package thermal impedance, θJA: DB package: 70℃/W, DW package: 58℃/W, N package: 69℃/W, NS package: 60℃/W, PW package: 83℃/W; (7)Storage temperature range, Tstg: -65℃ to 150℃.
