TECHNICAL DATA

KK74LV245

==OCTAL BUS TRANSCEIVER; 3-State

The KK74LV245 is a low-voltage Si-gate CMOS device and is pin and function compatible with KK74HCT245. The KK74LV245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The KK74LV245 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. N SUFFIX PLASTIC DIP201201 • Output voltage levels are compatible with input levels of CMOS, NMOS and TTL ICS • Supply voltage range: 1.2 to 3.6 V • Low input current: 1.0 µА; 0.1 µА at Т = 25 °С • Output Current: 8 mA at VCC = 3.0 V • High Noise Immunity Characteristic of CMOS Devices DW SUFFIXSOORDERING INFORMATION KK74LV245DPlastic DIP KK74LV245DWSOIC TA = -40° to 125° C for all packages LOGIC DIAGRAM A0A1A2ADATAPORT23456789119PIN ASSIGNMENT 1817161514131211 PIN 20=VCC PIN 10 = GND B0B1B2B3B4B5B6B7BDATAPORTDIRA0A1A2A3A4A5A6A712345678910 20191817161514131211VCCOEB0B1B2B3B4B5B6B7A3A4A5A6A7DIRGNDOEFUNCTION TABLE Inputs Inputs/outputs OE DIRA B input BA Z L L AB L H input H X H= high level L = low level X = don’t care Z = high impedance Z

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused

outputs must be left open.
