TC74LCX163245FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX163245FT
16-Bit Dual Supply Bus Transceiver
The TC74LCX163245FT is a dual supply, advanced high-speed CMOS
16-bit dual supply voltage interface bus transceiver fabricated with
silicon gate CMOS technology.
Designed for use as an interface between a 3.3-V or a 2.5-V bus and a
5-V bus in mixed 3.3-V or 2.5-V/5-V supply systems, it achieves high-
speed operation while maintaining the CMOS low power dissipation. It
is intended for two-way asynchronous communication between data
busses.
The direction of data transmission is determined by the level of the
DIR input.
Weight: 0.25 g (typ.)
The enable input ( OE ) can be used to disable the device so that the
buses are effectively isolated. The B-port interfaces with the 3.3-V or
2.5-V bus, the A-port with the 5 V bus.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features (Note)
Bidirectional interface between 3.3 V or 2.5 V buses and 5 V buses Wide operating temperature range: Topr = -40 to 125 °C (Note 1) High-speed operation: tpd = 7.0 ns (max)
(VCCB = 3.3 ± 0.3 V / VCCA = 5 ± 0.5 V, Ta = −40 to 85°C) Low power dissipation: ICC = 80 µA (max) (Ta = −40 to 85°C) Symmetrical ouput impedance: IOUTB = ±24 mA (min)
IOUTA = ±24 mA (min) (VCCB = 3.0 V / VCCA = 4.5 V) Power-down protection provided on all inputs and outputs Allows A port and VCCA to float simultaneously in ...
