Product Summary
The IDT74LVC257AQ is a 32-bit buffer/driver. It is built using advanced dual metal CMOS technology. This high-speed, low power device offers bus/backplane interface capability with improved packing density. The IDT74LVC257AQ has a flowthrough organization for simplifying board layout. The three-state controls operate this device in a Quad-Nibble, Dual-Byte or single 16-bit word mode. All inputs are designed with hysteresis for improved noise margin. The IDT74LVC257AQ has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. The applications of the IDT74LVC257AQ include 3.3V high speed systems and 3.3V and lower voltage computing systems.
