IDTQS32245QG HIGH-SPEED CMOS QUICKSWITCH 8-BIT BUS SWITCH

Manufactured by IDT - QSOP20 SMD Package

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 74’245. The QS32245 has 25Ω 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.

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
• 25Ω resistors for low noise
• TTL-compatible control inputs
