  • Available in 20 pin SOIC and QSOP packages

描述

The QS3245 provides a set of eight high-speed CMOS TTL-compatible bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/ LS245 8-bit transceivers. The low ON resistance of the QS3245 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS3245 operates at -40C to +85C.
