SN74ABT863DBLE

The SN74ABT863DBLE belongs to 'ABT863 family which are 9-bit transceivers designed for asynchronous communication between data buses. The control-function implementation allows for maximum flexibility in timing. These SN74ABT863DBLE devices allow noninverted data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic levels at the output-enable (OEAB and OEBA) inputs. The outputs are in the high-impedance state during power up and power down. The outputs remain in the high-impedance state while the device is powered down. When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The SN54ABT863 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT863 is characterized for operation from -40°C to 8.

The features of SN74ABT863DBLE can be summarized as (1)state-of-the-art EPIC-B BiCMOS design significantly reduces power dissipation; (2)typical VOLP (output ground bounce) < 1 V at VCC = 5 V, TA = 25°C; (3)high-impedance state during power up and power down; (4)high-drive outputs (-32-mA IOH, 64-mA IOL); (5)latch-up performance exceeds 500 mA Per JESD 17; (6)ESD Protection exceeds 2000 V per MIL-STD-883, method 3015; exceeds 200 V using machine model (C = 200 pF, R = 0); (7)package options include plastic small-outline (DW), shrink small-outline (DB) packages, and thin shrink small-outline (PW), ceramic chip carriers (FK), plastic(NT), and ceramic (JT) DIPs.

The absolute maximum ratings of SN74ABT863DBLE are (1)supply voltage range, VCC: -0.5 V to 7 V; (2)input voltage range, VI (except I/O ports) (see Note 1: -0.5 V to 7 V; (3)voltage range applied to any output in the high or power-off state, VO: -0.5 V to 5.5 V; (4)current into any output in the low state, IO: SN54ABT863: 96 mA/ SN74ABT863: 128 mA; (5)input clamp current, IIK (VI < 0):-18 mA; (6)output clamp current, IOK (VO < 0): -50 mA.; (7)package thermal impedance, JA (see Note 2): DB package: 104°C/W/DW package : 81°C/W/NT package: 67°C/W/PW package: 120°C/W; (8)storage temperature range, Tstg: -65°C to 150°C.(Stresses beyond those listed under "absolute maximum ratings" 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. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero)
