Functional Description
• 16-Bit Dual Supply Bus Transceiver with Series Resistor
General
The TC74LCXR163245 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. 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.
The 26 Ω series resistor helps reducing output overshoot and undershoot without external resistor.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features (Note)
(1) Operating voltage: 5.0 V-3.3 V / 5.0 V-2.5 V bidirectional interface
(2) Wide operating temperature range: Topr = -40 to 125 (Note 1)
(3) 26 Ω series resistors on outputs
(4) High-speed operation: tpd = 8.5 ns (max) (VCCB = 3.3±0.3 V, VCCA = 5.0±0.5 V, Ta = -40 to 85 )
(5) Low power dissipation: ICC = 80 μA (max) at Ta = -40 to 85
(6) Output current: IOUTA = ±12 mA (min)
IOUTB = ±12 mA (min)
(VCCA = 4.5 V / VCCB = 3.0 V)
(7) Power-down protection provided on all inputs and outputs
(8) Allows A port and VCCA to float simultaneously in high state at OE pin
(9) Package: TSSOP
