Description

The 74LV245 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT245.

The 74LV245 is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The 74LV245 features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control.OE controls the outputs so that the buses are effectively isolated.

The 74LV245 is designed as a low-voltage si-gate CMOS device that is pin and function compatible with 74HC/HCT245. It is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74LV245 features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated.

The features of the 74LV245. The first one is wide operating voltage from 1.0 to 5.5V. The second one is optimized for low voltage applications from 1.0 to 3.6V. The third one is accepts TTL input levels between Vcc=2.7V and Vcc=3.6V. The fourth one is typical Volp (output ground bounce) < 0.8 V at Vcc=3.3V, Tamb = 25°C. The fifth one is typical Vohv (output Voh undershoot) > 2V at Vcc=3.3V, Tamb = 25°C. The sixth one is its output capability is bus driver. The seventh one is its ICC category is MSI. That are all the main features.

Some absolute maximum ratings of the 74LV245 have been concluded into several points as follow. The first one is about its DC supply voltage which would be from 0.5 to +7.0V. The second one is about its DC input diode current which would be 20mA. The third one is about its DC output diode current which would be 50mA. The fourth one is about its DC output source or sink current standard outputs which would be 35mA. The fifth one is about its DC Vcc or GND current for types with standard outputs which would be 70mA. The sixth one is about its storage temperature range which would be from 65 to +150°C. The seventh one is about its power dissipation per package which would be 750mW for plastic DIL and would be 500mW for plastic mini-pack (SO) and would be 400mW for plastic shrink mini-pack (SSOP and TSSOP). It should be noted that stresses beyond those listed may cause permanent damage to the device. Exposure to absolute maximum rated conditions of the 74LV245 for extended periods may affect device reliability. And so on. For more information please contact us for details.
