IDT74LVCHR162245A 3.3V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS EXTENDED COMMERCIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74LVCHR162245A BUS TRANSCEIVER WITH 3 STATE OUTPUTS, 5 VOLT TOLERANT I/O, BUS-HOLD DESCRIPTION FEATURES: - - - - - - - - - Typical tSK(0) (Output Skew) < 250ps ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) 0.635mm pitch SSOP, 0.50mm pitch TSSOP and 0.40mm pitch TVSOP packages Extended commercial range of -40C to +85C VCC = 3.3V 0.3V, Normal Range VCC = 2.7V to 3.6V, Extended Range CMOS power levels (0.4 W typ. static) All inputs, outputs and I/O are 5 Volt tolerant Supports hot insertion This 16-bit bus transceiver is built using advanced dual metal CMOS technology. This high-speed, low power device is ideal for asynchronous communication between two buses (A and B). The Direction and Output Enable controls are designed to operate this device as either two independent 8-bit transceivers or one 16-bit transceiver. The direction control pin (DIR) controls the direction of data flow. The output enable pin (OE) overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin. All pins 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. Drive Features for LVCHR162245A: - Balanced Output Drivers: 12 mA - Low switching noise. The LVCHR162245A has series resistors in the device output structure which will significantly reduce line noise when used with light loads. The driver has been designed to drive 12mA at the designated threshold levels. APPLICATIONS: * 5V and 3.3V mixed voltage systems * Data communication and telecommunication systems The LVCHR162245A has "bus-hold" which retains the input's last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors.
