1 / 9 page 16-Bit Latch CY74FCT163373 SCCS053 - March 1997 - Revised March 2000 Data sheet acquired from Cypress Semiconductor Corporation. Data sheet modified to remove devices not offered. Copyright © 2000, Texas Instruments Incorporated Features • Low power, pin-compatible replacement for LCX and LPT families • 5V tolerant inputs and outputs • 24 mA balanced drive outputs • Power-off disable outputs permits live insertion • Edge-rate control circuitry for reduced noise • FCT-C speed at 4.2 ns • Latch-up performance exceeds JEDEC standard no. 17 • Typical output skew < 250 ps • Industrial temperature range of –40˚C to +85˚C • TSSOP (19.6-mil pitch) or SSOP (25-mil pitch) • Typical Volp (ground bounce) performance exceeds Mil Std 883D •VCC = 2.7V to 3.6V • ESD (HBM) > 2000V Functional Description This device is a 16-bit, D-type latch, designed for use in bus applications requiring high speed and low power. It can either be used as two independent 8-bit latches, or as a single 16-bit latch by connecting the Output Enable (OE) and Latch (LE) inputs. The outputs are 24-mA balanced output drivers with current limiting resistors to reduce the need for external terminating resistors and provide for minimal undershoot and reduced ground bounce. Flow-through pinout and small shrink packaging aid in simplifying board layout. The CY74FCT163373 is designed with inputs and outputs capable of being driven by 5.0V buses, allowing its use in mixed voltage systems as a translator. The outputs are also designed with a power off disable feature enabling its use in applications requiring live insertion.
