描述
The QS3253 is a high-speed CMOS TTL-compatible dual 4:1 multiplexer/demultiplexer with 3-state outputs. The QS3253 is a function and pinout-compatible version of the 74F253, 74FCT253, and 74ALS/AS/LS253 dual 4:1 multiplexers. The low ON-resistance of the QS3253 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS3253 operates at -40 °C to +85 °C.
特性
- Enhanced N-channel FET with no inherent diode to VCC
- 5Ω bidirectional switches connect inputs to outputs
- Zero propagation delay, zero ground bounce
- Undershoot clamp diodes on all switch and control inputs
- TTL-compatible control inputs
- Available in 16-pin QSOP and S1 packages
