74LVC1284
FEATURES
· Asynchronous operation · 4-Bit transceivers · 3 additional buffer/driver lines · TTL compatible inputs · ESD protection exceeds 1000V per MIL STD 883 Method 3015
and 200V per Machine Model
DESCRIPTION
The 74LVC1284 parallel interface chip is designed to provide an asynchronous, 4-bit, bi-directional, parallel printer interface for personal computers. Three additional lines are included to provide handshaking signals between the host and the peripheral. The part is designed to match IEEE 1284 standard. The 4 transceiver pins (A/B 1-4) allow data transmission from the A bus to the B bus, or from the B bus to the A bus, depending on the state of the direction pin DIR. The B bus and the Y5-Y7 lines have totem pole or open drain style outputs depending on the state of the high drive enable pin HD. The A bus only has totem pole style outputs. All inputs are TTL compatible with at least 300mV of input hysteresis at VCC = 3.3V.
· Input Hysteresis · Low Noise Operation · Center Pin VCC & GND · IEEE 1284 Compliant Level 1 & 2 · Overvoltage Protection on B side

NOTES: 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 voltage ratings may be exceeded if the input and output current ratings are observed. 4. VOUT B/Y (tr) guarantees only that this part will not be damaged by reflections in application so long as the voltage levels remain in the specified range.
