产品信息

The MC74VHC245 is an advanced high speed CMOS octal bus transceiver fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
It is intended for two-way asynchronous communication between data buses. The direction of data transmission is determined by the level of the DIR input. The output enable pin (OE) can be used to disable the device, so that the buses are effectively isolated.
All inputs are equipped with protection circuits against static discharge.

High Speed: t
= 4.0ns (Typ) at V
= 5V
Low Power Dissipation: I
= 4µA (Max) at T
= 25 C
High Noise Immunity: V
= V
= 28% V
Power Down Protection Provided on Inputs
Balanced Propagation Delays
Designed for 2V to 5.5V Operating Range
Low Noise: V
= 1.2V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300mA
ESD Performance: HBM > 2000V; Machine Model > 200V
Chip Complexity: 308 FETs or 77 Equivalent Gates
APPLICATION NOTES
Do not force a signal on an I/O pin when it is an active output,
damage may occur.
All floating (high impedance) input or I/O pins must be fixed by
means of pull up or pull down resistors or bus terminator ICs.
A parasitic diode is formed between the bus and VCC terminals.
Therefore, the VHC245 cannot be used to interface 5V to 3V systems
directly.
These devices are available in Pb-free package(s). Specifications herein apply to both standard and Pb-free devices. Please see our website at www.onsemi.com for specific Pb-free orderable part numbers, or contact your local ON Semiconductor sales office or representative.
