74LVT245D

The 74LVT245D belongs to LVT245 family which is a high-performance BiCMOS product designed for VCC operation at 3.3V and it is also an octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an Output Enable (OE) input for easy cascading and a Direction (DIR) input for direction control.

The features of 74LVT245D can be summarized as (1)octal bidirectional bus interface; (2)3-state buffers; (3)output capability: +64mA/-32mA; (4)TTL input and output switching levels; (5)input and output interface capability to systems at 5V supply; (6)bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs; (7)live insertion/extraction permitted; (8)power-up 3-state; (9)no bus current loading when output is tied to 5V bus; (10)latch-up protection exceeds 500mA per JEDEC Std 17; (11)ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per machine model.

The absolute maximum ratings of 74LVT245D are (1)VCC DC supply voltage: -0.5 to +4.6 V; (2)IIK DC input diode current (VI < 0): -50 mA; (3)VI DC input voltage3: -0.5 to +7.0 V; (4)IOK DC output diode current(VO < 0): -50 mA; (5)VOUT DC output voltage3(output in off or high state): -0.5 to +7.0V; (6)IOUT DC output current(output in low state/output in high state): 128/-64mA; (7)Tstg storage temperature range: -65 to 150 °C.(1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.).
