Description

The 74LV245N belongs to 74LV245 family which 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 features of 74LV245N can be summarized as (1)optimized for low voltage applications: 1.0 to 3.6V; (2)accepts TTL input levels between VCC = 2.7V and VCC = 3.6V; (3)typical VOLP (output ground bounce) <0.8V @ VCC = 3.3V, Tamb = 25°C; (4)typical VOHV (output VOH undershoot) <2V @ VCC = 3.3V, Tamb = 25°C; (5)wide operating voltage: 1.0 to 5.5 V; (6)output capability: bus driver; (7)ICC category: MSI.

The absolute maximum ratings of 74LV245N are (1)VCC DC supply voltage: -0.5 to +7.0 V; (2)±IIK DC input diode current(VI <-0.5 or VI > VCC + 0.5V): 50mA; (3)±IOK DC output diode current(VO < -0.5 or VO > VCC + 0.5V): 35mA; (4)±IO DC output source or sink current -bus driver outputs(-0.5V < VO < VCC + 0.5V): 35mA; (5)±IGND, ±ICC DC VCC or GND current for types with bus driver outputs: 70mA; (6)Tstg storage temperature range: -65 to +150 °C; (7)power dissipation per package for temperature range: -40 to +125°C-plastic DIL(above +70°C derate linearly with 12mW/K)/-plastic mini-pack (SO)(above +70°C derate linearly with 8 mW/K)/-plastic shrink mini-pack (SSOP and TSSOP)(above +60°C derate linearly with 5.5 mW/K): 750/500/400mW.(1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the 74LV245N at these or any other conditions beyond those indicated under arecommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The input and output voltage ratings of the 74LV245N may be exceeded if the input and output current ratings are observed.)
