IDT74ALVCH16901 3.3V CMOS 18-BIT UNIVERSAL TRANSCEIVER WITH PARITY
3.3V CMOS 18-BIT IDT74ALVCH16901 UNIVERSAL TRANSCEIVER ADVANCE WITH PARITY GENERATORS/ INFORMATION CHECKERS BUS-HOLD
MICRON CMOS Technology Typical tSK(0) (Output Skew) 250ps 2000V MIL-STD-883, Method 3015; 200V using machine model 200pF, 0.50mm pitch TSSOP package Extended commercial range 40°C 85°C 3.3V 0.3V, Normal Range 2.7V 3.6V, Extended Range 2.5V 0.2V CMOS power levels (0.4µ typ. static) Rail-to-Rail output swing increased noise margin
DESCRIPTION:
This 18-bit universal transceiver built using advanced dual metal CMOS technology. ALVCH16901 dual 9-bit dual 9-bit parity transceiver with registers. device operate feed-through transceiver generate/check parity from 8-bit data buses either direction. ALVCH16901 features independent clock (CLKAB CLKBA), latch-enable (LEAB LEBA), dual 9-bit clock enable (CLKENAB CLKENBA) inputs. also provides parity-enable (SEL) parity-select (ODD/EVEN) inputs separate error-signal (ERRA ERRB) outputs checking parity. direction data flow controlled OEAB OEBA. When low, parity functions enabled. When high, parity functions disabled device acts 18-bit registered transceiver. ALVCH16901 been designed with ±24mA output driver. This driver capable driving moderate heavy load while maintaining speed performance. ALVCH16901 "bus-hold" which retains inputs' last state whenever input goes high impedance. This prevents floating inputs eliminates need pull-up/down resistors.
