8-BIT BUS SWITCH
IDTQS32245
.EATURES:
⢠Enhanced N channel FET with no inherent diode to Vcc
⢠5⦠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
⢠25⦠resistors for low noise
⢠TTL-compatible control inputs
⢠Available in SOIC, QSOP, and TSSOP packages
DESCRIPTION:
The QS32245 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 Output Enable (OE) signal turns the switches
on similar to the OE signal of the 74â245. The QS32245 has 25⦠series
resistors to reduce ground bounce noise.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
The QS32245 is characterized for operation at -40°C to +85°C.
APPLICATIONS:
⢠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
