Octal d-type latch (3-state)
TECHNICAL DATA
IN74VHCT373
IN74VHCT373 is designed for using in up-to-date high
performance computers, high-level electronic equipment
for mass application.
IN74VHCT373 is identical in pinout to the ICs
IN74HC373A, IN74HCT373A, IN74AC373A,
IN74ACT373A.
Input voltage levels are compatible with standard TTL-
levels. Output voltage levels are compatible with input
levels of C-MOS, N-MOS and TTL ICs.
ORDERING INFORMATION
IN74VHCT373N Plastic
IN74VHCT373DW SOIC
TA = -40° to 85° C for all packages
Features:
• Supply voltage range 4.5 to 5.5 V.
• Output current 8 mA.
• Low consumption current: 0.2 mkA (typical value) at Та = 25 °С.
• Latchup current not less than 300 mA at Та = 85 °С.
• Tolerable value of static potential not less than 2000 V as per human body model
(HBM) and not less than 200 V as per machine model (ММ).
• Ambient operation temperature minus 40 to plus 85 °С.
• Balanced signal propagation delay.
• Ensures voltage exceeding mode on input
