Description
The QS3245 is a set of eight high-speed CMOS TTL-compatible bus switches, designed to provide faster speed than conventional logic devices. It features a low ON resistance that allows inputs to be connected to outputs without adding propagation delay and generating additional ground bounce noise. In addition, the Output Enable (OE) signal turns the switches on similar to the OE signal of the 74’245. This Electronic Component Model is pinout compatible with 74FCT245, 74F245, 74ALS/AS/LS245 8-bit transceivers. The QS3245 is characterized for operation at -40°C to +85°C.
Specifications and features
- Enhanced N channel FET with no inherent diode to Vcc
- 5Ω bidirectional switches connect inputs to outputs
- Pin compatible with the 74F245, 74FCT245, and 74FCT245T
- Low power CMOS proprietary technology
- Zero propagation delay, zero ground bounce
- Undershoot clamp diodes on all switch and control inputs
- TTL-compatible control inputs
- Available in SOIC and QSOP packages
Application Scenarios
The QS3245 is ideal for hot-swapping, hot-docking; voltage translation (5V to 3.3V); power conservation; capacitance reduction and isolation; logic replacement (data processing), clock gating, bus switching and isolation.
