74ABT16541
16-Bit Buffer/Line Driver with 3-STATE Outputs
General Description
The ABT16541 contains sixteen non-inverting buffers with
3-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmit-
ter/receiver. The device is byte controlled. Individual 3-
STATE control inputs can be shorted together for 8-bit or
16-bit operation.
Features
s Separate control logic for each nibble
s 16-bit version of the ABT541
s Outputs sink capability of 64 mA, source capability of
32 mA
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed latchup protection
s High impedance glitch free bus loading during entire
power up and power down cycle
s Non-destructive hot insertion capability

Note 11: This specification is guaranteed but not tested. The limits apply to propagation delays for all paths described switching in phase
(i.e., all LOW-to-HIGH, HIGH-to-LOW, etc.)
Note 12: These specifications guaranteed but not tested. The limits represent propagation delays with 250 pF load capacitors in place of the 50 pF load
capacitors in the standard AC load.
Note 13: Skew is defined as the absolute value of the difference between the actual propagation delays for any two separate outputs of the same device.
The specification applies to any outputs switching HIGH-to-LOW (tOSHL), LOW-to-HIGH (tOSLH), or any combination switching LOW-to-HIGH and/or HIGH-
to-LOW (tOST). The specification is guaranteed but not tested.
Note 14: This describes the difference between the delay of the LOW-to-HIGH and the HIGH-to-LOW transition on the same pin. It is measured across all
the outputs (drivers) on the same chip, the worst (largest delta) number is the guaranteed specification. This specification is guaranteed but not tested.
Note 15: Propagation delay variation for a given set of conditions (i.e., temperature and VCC) from device to device. This specification is guaranteed but not
tested.
