This 16-bit (dual-octal) noninverting bus transceiver contains two separate supply rails. B port has VCCB, which is set to operate at 3.3 V and 5 V. A port has VCCA, which is set to operate at 2.5 V and 3.3 V. This allows for translation from a 2.5-V to a 3.3-V environment, and vice versa, or from a 3.3-V to a 5-V environment, and vice versa.
The SN74ALVC164245 is designed for asynchronous communication between data buses. The control circuitry (1DIR, 2DIR, 1OE, and 2OE) is powered by VCCA.
To ensure the high-impedance state during power up or power down, the output-enable (OE) input should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.

2. 商品都是原装正品吗?
答:我们的自营商品均采自合作的国内外原厂或授权代理商,来源均可追溯,确保原装正品。
3.可以提供原厂或代理的资质证明吗?
答:目前我们自营代理的品牌包含滨松,USHIO,新唐科技等一线品牌,其他渠道均为原厂及代理渠道。如有需要,我们可以针对具体品牌型号来沟通确认。
4.我可以通过BOM单进行询价吗?
答:为客户提供极具行业特色的电子元器件BOM表一站式供应链解决方案,只需联系商城客服提交物料清单,即可获得报价。
5.下单后什么时候能发货?多久能到?
答:大部分商品信息中都有标注货期,您可根据货期估计商品的发货时间,具体到货时间根据商品具体所在的仓库、您所选择的物流方式而定。
6.能开发票吗?
答:可以为个人用户开具普通发票,也可以为企业用户开具增值税专用发票。
