FEATURES
• Asynchronous operation
DESCRIPTION
The 74HCT1284 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.
• 4-Bit transceivers
• 3 additional buffer/driver lines
• TTL compatible inputs
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.
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
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
• Input Hysteresis
• Low Noise Operation
compatible with at least 400mV of input hysteresis at V = 5.0V.
CC
• Center Pin V & GND
CC
• 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.
