Part Details:

74ACT16245 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS (NON INVERTED) s HIGH SPEED: tPD = 4.9ns (TYP.) at VCC = 5V s LOW POWER DISSIPATION:ICC = 8µA(MAX.) at TA=25°C s COMPATIBLE WITH TTL OUTPUTSVIH = 2V (MIN.), VIL = 0.8V (MAX.) s 50 TRANSMISSION LINE DRIVINGCAPABILITY TSSOP s SYMMETRICAL OUTPUT IMPEDANCE:|IOH| = IOL = 24mA (MIN) s OPERATING VOLTAGE RANGE: ORDER CODES VCC (OPR) = 4.5V to 5.5V PACKAGE TUBE T & R s IMPROVED LATCH-UP IMMUNITY TSSOP 74ACT16245TTR DESCRIPTIONThe 74ACT16245 is an advanced high-speed PIN CONNECTION CMOS 16-BIT BUS TRANSCEIVER (3-STATE)fabricated with sub-micron silicon gate anddouble-layer metal wiring C2MOS technology.This IC is intended for two-way asynchronouscommunication between data buses and thedirection of data transmission is determined byDIR input. The enable inputs G can be used todisable the device so that the buses are effectivelyisolated.All floating bus terminals during the Z-state mustbe held HIGH or LOW.All inputs and outputs are equipped with protec-tion circuits against static discharge, giving them2KV ESD immunity and transient excess voltage.
