IDT74LVCH16240A 3.3V CMOS 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS
3.3V CMOS IDT74LVCH16240A 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS, VOLT TOLERANT I/O, BUS-HOLD
Typical tSK(0) (Output Skew) 250ps 2000V MIL-STD-883, Method 3015; 200V using machine model 200pF, 0.635mm pitch SSOP, 0.50mm pitch TSSOP 0.40mm pitch TVSOP packages Extended commercial range -40°C +85°C 3.3V ±0.3V, Normal Range 2.7V 3.6V, Extended Range CMOS power levels (0.4µ typ. static) inputs, outputs Volt tolerant Supports insertion
DESCRIPTION:
This 16-bit buffer/driver built using advanced dual metal CMOS technology. This high-speed, power device designed specifically improve both performance density 3-state memory address drivers, clock drivers, bus-oriented receivers transmitters. device used four 4-bit buffers, 8-bit buffers, 16-bit buffer. This device provides inverting outputs symmetrical active-low outputenable (OE) inputs. ensure high-impedance state during power power down, should tied through pullup resistor; minimum value resistor determined current-sinking capability driver. pins this 16-bit buffer/line driver driven from either 3.3V devices. This feature allows device translator mixed 3.3V/5V supply system. LVCH16240A "bus-hold" which retains inputs' last state whenever input goes high impedance. This prevents floating inputs eliminates need pull-up/down resistors. LVCH16240A been designed with ±24mA output driver. driver capable driving moderate heavy load while maintaining speed performance.
Drive Features LVCH16240A High Output Drivers: ±24mA Reduced system switching noise
