IDT74LVCH16543A 3.3V CMOS 16-BIT REGISTERED TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74LVCH16543A REGISTERED TRANSCEIVER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O, BUS-HOLD DESCRIPTION FEATURES: The LVCH16543A 16-bit registered transceiver is built using advanced dual metal CMOS technology. The LVCH16543A can be used as two 8-bit transceivers or one 16-bit transceiver. Separate latch-enable (LEAB or LEBA) and output-enable (OEAB or OEBA) inputs are provided for each register to permit independent control in either direction of data flow. The A-to-B enable (CEAB) input must be low in order to enter data from the A port or to output data from the B port. LEAB controls the latch function. When LEAB is low, the A to B latches are transparent. A subsequent low-to-high transition of LEAB puts the A latches in the storage mode. OEAB performs output enable function on the B port. Data flow from the B port to the A port is similar but requires using CEBA, LEBA, and OEBA inputs. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin. All pins of this 16-bit registered transceiver can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system. The LVCH16543A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. The LVCH16543A has “bus-hold” which retains the inputs’ last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. • Typical tSK(o) (Output Skew) < 250ps • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • VCC = 3.3V ± 0.3V, Normal Range • VCC = 2.7V to 3.6V, Extended Range μ W typ. static) • CMOS power levels (0.4μ • All inputs, outputs, and I/O are 5V tolerant • Supports hot insertion • Available in TSSOP package DRIVE FEATURES: • High Output Drivers: ±24mA • Reduced system switching noise APPLICATIONS: • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 1OEBA 56 2OEBA 29 2CEBA 31 1CEBA 54 30 1LEBA 55 2LEBA 1OEAB 1 2OEAB 1CEAB 3 2CEAB 1LEAB 2 2LEAB 27 1A1 5 C1 2A1 1D 52 28 26 C1 15 42 1B1 1D C1 C1 1D 1D 2B1 TO SEVEN OTHER CHANNELS TO SEVEN OTHER CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.
