True ±24mA Balanced Drive @ 3.3V The PI74AVC+16373 is particularly suited for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. This device can be used as two 8-bit latches or one 16-bit latch. When the Latch Enable (LE) input is HIGH, the Q outputs follow the (D) inputs. When LE is taken LOW, the Q outputs are latched at the levels set up at the D inputs. Compatible with Philips and T.I. AVC Logic family IOFF supports partial power-down operation 3.6V I/O Tolerant inputs and outputs All outputs contain a patented DDC (Dynamic DriveControl) circuit that reduces noise without degrading propagation delay. A buffered Output Enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state in which the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without need for interface or pullup components. OE does not affect internal operations of the latch. Old data can be retained or new data can be entered while the outputs are in the high impedance state. Industrial operation at 40°C to +85°C Available Packages: 48-pin 240-mil wide plastic TSSOP 48-pin 173-mil wide plastic TVSOP Logic Block Diagram 1OE 1LE To ensure the high impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 1 48 C1 2 1D1 47 1Q1 1D To Seven Other Channels 2OE 2LE 24 25 C1 13 2D1 36 2Q1 1D To Seven Other Channels 1 PS8526 03/01/01 PI74AVC+16373 2.5V 16-Bit Transparent D-Type Latch with 3-State Outputs 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Maximum Ratings (Above which the useful life may be impaired.

E. tPLZ and tPHZ are the same as tdis F. tPZL and tPZH are the same as ten G. tPLH and tPHL are the same as tpd 9 PS8526 03/01/01 PI74AVC+16373 2.5V 16-Bit Transparent D-Type Latch with 3-State Outputs 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Packaging Mechanical - 48-pin TSSOP (A-package) 48 .236 .244 1 6.0 6.2 .488 12.4 .496 12.6 .047 1.20 Max SEATING PLANE .004 0.09 .008 0.20 X.XX X.XX DENOTES DIMENSIONS IN MILLIMETERS .0197 BSC 0.50 0.45 .018 0.75 .030 .002 .006 0.05 0.15 .007 .010 0.17 0.27 .319 BSC 8.1 Packaging Mechanical - 48-pin TVSOP (TSSOP) (K-package) 48 .169 .177 4.30 4.50 .0035 .008 .031 .041 0.80 1.05 1 .378 9.60 .386 9.80 0.09 0.20 0.45 .018 0.75 .030 .252 BSC 6.4 SEATING PLANE X.XX DENOTES DIMENSIONS X.XX IN MILLIMETERS .016 BSC 0.40 .0051 .009 0.13 0.23 .002 .006 0.05 0.15 Max. .047 1.20 Orde ring Information De s cription PI74AVC+16373A 48- pin, 240- mil wide plastic TSSO P PI74AVC+16373K 48- pin, 173- mil wide plastic TVSOP Pericom Semiconductor Corporation 2380 Bering Drive • San Jose, CA 95131 • 1-800-435-2336 • Fax (408) 435-1100 • http://www.pericom.com 10 PS8526 03/01/01
