74ABT9253N

The 74ABT9253N belongs to 74ABT2953 family which is high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. Two 8-bit back-to-back registers store data flowing in both directions between two bidirectional buses. The 74ABT2953 device is an 8-bit registered inverting transceiver. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (OEXX) is Low. Data flow from A inputs to B outputs is the same as for B inputs to A outputs. Data applied to the inputs is entered and stored on the rising edge of the Clock (CPXX) provided that the Clock Enable (CEXX) is Low.

The features of 74ABT9253N can be summarized as (1)8-bit registered transceiver; (2)independent registers for A and B buses; (3)output capability: +64mA/±32mA; (4)latch-up protection exceeds 500mA per Jedec Std 17; (5)ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per machine model; (6)live insertion/extraction permitted; (7)power-up 3-state; (8)power-up reset.

The absolute maximum ratings of 74ABT9253N are (1)VCC DC supply voltage: -0.5 to +7.0V; (2)IIK DC input diode current(VI < 0): -18mA; (3)VI DC input voltage3: -1.2 to +7.0V; (4)IOK DC output diode current(VO < 0): -50mA; (5)VOUT DC output voltage3(output in off or high state): -0.5 to +5.5; (6)V; (7)IOUT DC output current(output in Low state): 128mA; (8)Tstg storage temperature range: -65 to 150°C.
