AT16244 Features • • • • • • • Fastest Propagation Speeds in the Industry TPD (F grade) = 2.5 ns, TPD (G grade) = 2.0 ns Maximum derating for capacitive loads 1.5ns/100 pF (F grade) and 1.1 ns/100 pF (G grade) Very low ground bounce < 0.6V @ VCC =5.00 V, Ta=25°C Excellent noise rejection Typical output skew ≤0.25ns Bus Hold circuitry to retain last active state during Tri-State™ Available in SSOP and TSSOP packages Description Atmel’s Fast Logic 16-Bit Buffer/Line driver provides bus interface and signal buffering at the fastest speeds available in the industry. The Tri-state outputs can be set for either 4-bit, 8-bit, or 16-bit independent operation. The AT16244 also has bus-hold circuitry which retains the last state of the input whenever a high impedance level is detected, and eliminates the need for pull-up or pull-down resistors. Minimal ground bounce and high input noise rejection make this device excellent for use in all high speed interface applications.

X = Don’t Care, Z = High Impedance *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Notes: 1. Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is VCC +0.75V dc which may overshoot to +7.0V for pulses of less than 20 ns.
