DESCRIPTION
LVCH16543A 16-bit registered transceiver built using advanced dual metal CMOS technology. LVCH16543A used 8bit transceivers 16-bit transceiver. Separate latch-enable (LEAB LEBA) output-enable (OEAB OEBA) inputs provided each register permit independent control either direction data flow. A-to-B enable (CEAB) input must order enter data from port output data from port. LEAB controls latch function. When LEAB low, latches transparent. subsequent lowto-high transition LEAB puts latches storage mode. OEAB performs output enable function port. Data flow from port port similar requires using CEBA, LEBA, OEBA inputs. Flow-through organization signal pins simplifies layout. inputs designed with hysteresis improved noise margin. pins this 16-bit registered transceiver driven from either 3.3V devices. This feature allows this device translator mixed 3.3V/5V supply system. LVCH16543A been designed with 24mA output driver. This driver capable driving moderate heavy load while maintaining speed performance. LVCH16543A "bus-hold" which retains inputs' last state whenever input goes high impedance. This prevents floating inputs eliminates need pull-up/down resistors.
Drive Features LVCH16543A: High Output Drivers: ±24mA Reduced system switching noise
